Woman charged with attempted murder of two boys with 'noxious substance'

A woman has been charged with the attempted murder of two children following an alleged domestic violence incident in Brisbane's north-west.

Police allege the 47-year-old woman exposed two boys, aged 12 and 15, to a noxious substance at a home in Mitchelton on September 24.

A 70-year-old man attending the residence noticed the noxious substance and the matter was reported to police.

The boys were not injured and police said they are "safe and well".

The woman was taken to hospital for medical treatment.

She was discharged from hospital today and arrested by police.

She has since been charged with two counts of attempted murder as a domestic violence offence against a child.

She is expected to appear in Brisbane Magistrates Court this afternoon.
