A MALE Sergeant from South East Metropolitan Response received a serious knife injury to his leg overnight.
The officer was responding to an incident involving a 46 year-old man threatening self-harm about 3am this morning, outside the Gosnells Police Station on Albany Highway,
Protracted negotiations with the man failed and officers attempted to physically disarm the man and subdue him.
During the struggle, the officer allegedly received a serious stab wound to his lower leg.
He was taken to Armadale Hospital and received several stitches to the wound; he has since been released.
The 46-year-old man was also taken to hospital for a health assessment; he has been charged with going armed in public as to cause fear and unlawful wounding.
He will appear before the Northbridge Magistrates Court tomorrow.
