A suitcase full of suffering: Malaysia's role in the illegal gibbon trade

FOUR siamangs and three agile gibbons were found in a Mumbai hotel in May last year, after reportedly being flown from Malaysia concealed in suitcases.

All seven were dead.

Their story appears in a new report by wildlife trade monitoring organisation TRAFFIC. It is a grim reminder of what can happen beyond the airport seizure photographs, where officers stand beside recovered animals and the discovery appears to mark a happy ending.

In Mumbai, there was nothing left to rescue.

Demand for exotic pets helps drive this trade in living animals taken from the forest. Researchers say some gibbons may also be destined for captive facilities, although the buyers behind particular shipments remain unclear.

Finding out who wants these animals and who supplies them is an important part of the investigation.

The trade depends on turning a wild animal into something a person can own. The price paid by the animal begins long before it reaches a buyer.

Gibbons are small apes, a group that includes siamangs. They live in the forests of South and Southeast Asia, swinging through the treetops on long arms and producing remarkable songs that can carry for kilometres. Many species perform complex duets, making their presence heard far beyond the branches where they sit.

They also grow up in close family groups, with young remaining beside their parents for several years. These are animals with a place in the forest and a family around them. Inside a suitcase, both have been taken away.

TRAFFIC's Canopy to Cabin: Southeast Asia's Gibbon Smuggling by Air report records at least 86 gibbons intercepted in 33 airport smuggling incidents between January 2024 and August 2026. Each case involved Southeast Asia as a source or transit region, with the animals moving largely towards India.

That is 86 gibbons in just 32 months. And those are only the ones recorded in seizures.

"The smuggling of just a few gibbons on each flight may seem small in isolation, but like a dripping tap, the losses accumulate over time. What appears as minor incident by incident can add up to a devastating toll on wild populations," says TRAFFIC Southeast Asia director Kanitha Krishnasamy.

THE FAMILY LEFT BEHIND

A young gibbon recovered at an airport may represent more than one life lost from the forest. Adults can be harmed or killed when infants or juveniles are captured, the report explains, so taking a single youngster can mean breaking apart an entire family.

Any adults killed during capture will never appear in the airport tally. Their loss remains behind, where the capture took place.

Every gibbon whose life stage was known in TRAFFIC's airport records was an infant or juvenile. Their small size makes them easier to carry and conceal, a vulnerability traffickers exploit when moving them across borders. In the cases examined, animals were found in small pet carriers or plastic baskets inside checked-in suitcases for journeys lasting several hours.

Drawing on accounts of the wider trade, the report describes animals typically drugged before being stuffed into luggage or packages and transported without food or water. Many do not survive the journey. For those that do, arrival means they have endured capture, separation and confinement, with their eventual fate still uncertain.

All 20 recognised gibbon species face serious threats, including habitat loss, hunting and the live animal trade. Removing young animals adds to those pressures, while the harm done to their families makes the true cost greater than the number offered for sale.

A buyer may see only a small, appealing animal. The story of how it became available can be far harder to look at.

A ROUTE THROUGH MALAYSIA

For Malaysians, this trade passes through somewhere familiar. Kuala Lumpur International Airport (KLIA) was the most frequently implicated airport in the study, linked to 16 incidents involving at least 54 gibbons.

Ten seizures took place at KLIA itself, involving 32 animals. In four other incidents, the airport was identified as the departure point, while two involved transit through it. An animal's passage through KLIA does not establish where it was captured, but the repeated use of the airport shows how traffickers exploit Malaysia's international connections.

One image in the report makes that connection especially uncomfortable. An X-ray of luggage seized at KLIA in July 2025 reveals a siamang and other wildlife inside. Another photograph shows a gibbon found alongside a pair of cuscus in a Malaysian man's luggage that September.

An ordinary passenger's bag can conceal an extraordinary amount of suffering.

Siamangs and agile gibbons were the most frequently reported species in the seizures. Both habitate Peninsular Malaysia, Sumatra and Thailand — countries that also featured prominently as departure points for the smuggled animals.

More than half the 33 incidents were intercepted by Indian customs authorities. Malaysia recorded 10 interceptions and Thailand three, all involving gibbons destined for India.

Two attempts stopped in Indonesia had Oman and Dubai as their reported destinations. Chennai and Kempegowda, serving Bengaluru, were among the most frequently implicated Indian airports.

Wong Jye Wen, TRAFFIC's data and research officer for Southeast Asia, says the region "continues to be a critical hub linking wildlife supply chains to markets elsewhere in Asia".

She warns that "traffickers continue to adapt as enforcement efforts increase".

The report points to the February 2025 arrest of two Singaporean brothers arriving in Port Blair from Kuala Lumpur with eight infant primates. A new Singapore to Port Blair service via Kuala Lumpur had begun only months earlier. Researchers suggest the case may indicate attempts to exploit alternative routes into India, showing how a new connection for travellers can also create an opening for traffickers.

BEYOND THE PERSON WITH THE BAG

At least 38 people were arrested in connection with the airport incidents. At least eight were reported to have acted as couriers, or "mules", with several allegedly recruited through offers of cash, return flights and accommodation in exchange for transporting wildlife. Some offers included business class tickets.

But catching the person carrying the bag is only part of the task. In one case cited by TRAFFIC, Indian authorities also detained someone waiting outside an airport to receive wildlife from an arriving courier. The report also cites accounts linking gibbon seizures in Mumbai to a Chennai-based gang recruiting couriers to smuggle animals from Thailand.

These cases put the receiving end of the trade firmly in focus. TRAFFIC identifies India as a destination market, and all 13 airport interceptions in Malaysia and Thailand involved gibbons bound for India. Following that trail to the receivers, buyers and organisers is crucial to dismantling the networks behind the suitcases.

The gibbons were often part of a larger shipment. At least 265 other animals, including langurs and macaques, were confiscated alongside them. These mixed consignments suggest a trade capable of gathering different species and moving them towards the same market.

Understanding who orders and receives the animals is essential to stopping that trade. TRAFFIC calls for investigations that connect the hunters and collectors to the transporters, buyers and people organising the business behind them.

All gibbon species are protected under national wildlife laws across their range. International commercial trade in wild-caught gibbons is prohibited under CITES, the global convention regulating trade in endangered wildlife. Yet those protections depend on countries working together to detect the animals and pursue the people moving them.

There is some encouraging news. While seizures peaked in 2025, largely through interceptions in India, the first eight months of 2026 saw more detections in Malaysia and Thailand before the animals reached their intended overseas destinations.

That suggests earlier intervention along the route, although it does not establish whether the trade itself is growing or shrinking.

Seizure figures tell us what authorities find, leaving much of what escapes detection unknown.

Released in conjunction with World Gibbon Day on Oct 24, the report calls for better airport screening, trained staff and closer cooperation across borders. Each successful interception offers a chance to stop a journey before it ends as the one in Mumbai did.

For a young gibbon, the years ahead should be spent growing up beside its family, among branches and familiar calls. The seven found in that hotel were denied that future.

Their journey ended far from the trees that should have held them.
