The Ethical Standards Command is investigating with oversight from the Crime and Corruption Commission. Ms Linford said the incident was not being considered a terrorism event.

She said the body-worn camera footage was being reviewed and the GPS tracking device that Mr Abdi cut off was still missing.

She said police were searching for the driver of a white car who appeared to have stopped to help and spoke with Mr Abdi before leaving the scene.

Ms Linford said a “be alert” warning was sent to police and Mr Abhid’s associates would be questioned to understand what led him to the motorway.

Australian Federal Police Deputy Commissioner Investigations Ian McCartney confirmed Mr Abdi was known to counter-terrorism police as somebody who was suspected to be “influenced by Islamic State”.

“In May 2019,the deceased,who we suspect was influenced by Islamic State,attempted to depart Brisbane International Airport for Somalia,” he said.

“He was stopped and arrested on suspicion of an attempted foreign incursion.

“The deceased was released without charge due to insufficient evidence,however his passport was subsequently cancelled.”

The following month,Mr Abdi was charged with offences including failing to hand over the password to his mobile phone and remanded in custody. He applied for bail in September this year,which was granted under strict conditions,including that he wear the tracking device.

Lawyer for Mr Abdi’s family Terry O’Gorman was expected to respond to police’s comment later on Thursday afternoon.
