Doug Martin, a former NFL All-Pro running back, passed away on Saturday following an encounter with Oakland police officers, according to a source who confirmed the news to local affiliate KRON4.

Officers from the Oakland Police Department were dispatched just after 4:15 a.m. to the 11000 block of Ettrick Street in the Chabot Park area. They were responding to a report of a home intrusion, allegedly involving Martin. During this time, authorities were also informed that Martin was experiencing a medical emergency.

Upon arrival, police discovered Martin inside the residence and, after a brief struggle, took him into custody. Unfortunately, shortly afterward, Martin became unresponsive. He was transported to a local hospital, where he later passed away at the age of 36.
