A 55-year-old Bronx man has died in police custody, according to the NYPD.

Police say they responded to a call of a violent and emotionally disturbed person at an East 137th Street apartment Wednesday.

Officials say they were met at the door by a 59-year-old woman who told them the man, Richard Gonzales, was inside the apartment, acting violent and was possibly high on drugs.

Police say as the woman was explaining her story, the man opened the door of the apartment and attempted to pull her back inside. 

Police say after a brief struggle, they took the man into custody. Shortly after, according to police, the man began exhibiting signs of distress. Police say the man went limp, and they called an ambulance about a minute later.

Emergency responders arrived at the scene and provided medical aid to the 55-year-old, according to police.

They say he was transported to Lincoln Hospital where he was pronounced dead.

The Office of the Chief Medical Examiner conducted an examination of the incident, ruling their results inconclusive and said more testing still needs to be done.
