A man died Saturday morning after being arrested in Little Italy overnight near Grape Street and Columbia.
Police said they received a call Friday night about a naked man running around yelling for help.
The man began struggling after he was handcuffed by an officer.
A witness says the man injured his head when officers pinned him to the ground.
In a statement, San Diego police said their officers gave the man chest compressions until paramedics arrived and he was taken to the hospital where he was pronounced dead.
Investigators are at the scene looking for surveillance cameras to try to determine what caused the man’s death.
