A 23-year-old Afghan man has died in the Melbourne immigration detention centre.

Victoria police and the Australian Border Force confirmed that the man died around midnight on Friday.

“Police will prepare a report for the coroner following the death of a 23-year old-man at a government facility in Broadmeadows about 12.20am Saturday morning,” a spokesman for Victoria Police said.

“At this stage the death is not being treated as suspicious.”

A detainee at the Melbourne Immigration Transit Accommodation (Mita) told Guardian Australia he heard a commotion outside the man’s room and saw officers attempting to resuscitate him until paramedics arrived.

“He was laying down on the floor outside of his room,” he said.

“All the officers and managers, they were giving him CPR, for like 10 minutes. Then the ambulance came here. They continued that for like 45 or 50 minutes. After 50 minutes they took him away, he was dead.”

He said he knew the young man well. “Every morning he used to go to the internet room [to chat] with his mother on Skype,” he said.

“He was a very quiet guy. Five months ago he signed a visa to go out, I think a bridging visa. He signed because we have to sign first and then wait one or two weeks, but after five months he still didn’t go out.

“Nobody cares, nobody ever gives us any update.”

The detainee said he overheard an officer saying the young man’s medication had been stopped two days earlier.

“We don’t know how he died but we know that if something is wrong they don’t check up,” he said.

“He didn’t get the help he needed and he was so stressed and now he dies … His family will suffer forever.”

The Australian Border Force has been asked to confirm the circumstances of the man’s medication.

“We express our condolences to the man’s family and friends,” a spokesman for the force said.
