Homicide detectives are trying to determine whether there is anything suspicious about the death of a man, believed to be a former police officer, whose body was found at a Melbourne factory.
Officers found the man's body just before 10am on Friday at a commercial property at Braeside, south-east of Melbourne.
The man was a former Special Operations Group police officer, the Herald Sun reported, however police have yet to confirm if this is the case.
A 45-year-old man presented himself to Mordialloc Police Station early this morning leading to police checks at the Governor Road factory about 10am, where the body was found.
The man is now in custody and he and the dead man are believed to be known to each other.
"Investigators are in the process of identifying the deceased man and are making enquiries as to whether he is a former police officer," a police spokesperson said.
Traders who work near where the body was found told reporters people had visited the site on Thursday asking if a man in his 40s had been seen at the industrial estate.
"The family came looking," cafe owner Lee Le told the Herald Sun.
"We said we didn't see anyone.
"They kept looking and were looking in the paddocks.
"Today the police blocked off the street and said they found the body."
A woman, believed to be the man's mother, was seen trying to reach the location where the body was found.
"I want to see my son," a woman was heard saying on a 3AW report from the site.
Police are hoping to hear from anyone who may have witnessed any unusual activity in the area in recent days.
