Authorities are investigating the death of a 41-year-old man who died after being taken into custody by the Berkeley Police Department Tuesday for an involuntary psychiatric hold.

Officers detained the man after receiving calls about a person who possibly had mental health issues on the 2000 block of Allston Way, according to a statement from BPD.

The man became agitated when officers attempted to talk to him and a struggle ensued, the press statement continues.

“(He) became increasingly agitated and uncooperative to the officer’s verbal commands and began to scream and violently resist,” according to the statement. “After struggling with officers, they were able to gain control of the subject and place him in restraints.”

After being placed in restraints the man continued to kick and scream. He was then loaded onto an ambulance gurney and after a while police noticed the man was no longer breathing.

Authorities performed CPR on the man before being taken to a nearby hospital where he was later pronounced dead.

The identity of the man has not been released. The coroner’s office is currently not commenting on the incident.
