A 24-year-old man was found dead on a subway train in Brooklyn Friday night, police said.

Police were called to the Jay St./MetroTech station when passengers alerted them to an unconscious passenger on board an A train around 8:30 p.m.

The officers found the 24-year-old man toward the front of the train, police said. EMS workers then removed the man to Brooklyn Hospital where he was pronounced dead.

Police said the man’s body did not appear to have sustained any trauma. The Medical Examiner’s office will determine the official cause of death.

Police do not believe the man was the victim of a crime, officials said.
