The 27-year-old man who died under police custody lost his life due to drug overdose, Mexicali Police Chief Pedro Ariel Mendívil said.

The police chief explained that the man’s body had no signs of foul play.

The man died last week at the police headquarters after being arrested for a misdemeanor.

Chief Mendívil said the autopsy showed the man, whose identity was not revealed, previously consumed cocaine.

According to the police chief, the arrested man was transferred to another cell after turning violent.

The incident was turned to the state Attorney General’s office for investigation. The state Coroner’s office reported that the cause of death was acute respiratory insufficiency.
