A female Aboriginal inmate is in a critical condition after an alleged incident with a prison guard at Perth’s Bandyup Women’s Prison.

The West Australian reports the woman became unwell after being allegedly “body-slammed” by a prison guard, and was later admitted to the St John of God Midland Hospital.

A 2014 inspection of the Bandyup Women’s Prison found the prison population was above capacity and in a report the inspector described the prison as “the most neglected in the state.”

A Department of Justice spokesperson told media a review into the incident will be conducted.

The news comes on the same weekend a 40 year old Aboriginal man died in custody in Perth’s Acacia Prison, and as around the country tens of thousands marched calling for an end to Indigenous death’s in custody.
