Nepean Police Area Commander Detective Superintendent Trent King told media outside St Marys Police Station on Wednesday six teenagers, aged between 14 and 19, were in custody and being treated as persons of interest. There were three boys, a man and two girls among them.

A 15-year-old boy was subsequently also arrested at St Mary’s Police Station, taking the number of teenagers in custody to seven.

He said early investigations established the teenagers were not dining at the vicinity prior to the alleged stabbing, but it was too early to say what had happened prior to the incident and police were exploring a number of lines of inquiry.

“This was a man who was going about running his business within the local area, and certainly didn’t deserve what occurred,” he said.

“This was a gentleman who has suffered a gruesome injury and required immediate assistance, which unfortunately was unsuccessful in the end.”
