Former NFL player Douglas Martin, 36, has died while in police custody after an alleged “brief struggle occurred,” according to the Oakland Police Department (OPD).

The OPD released a statement via its Facebook page stating the department is investigating the “in-custody death” of the former Tampa Bay Buccaneers running back. The incident occurred on Oct. 18, after police officers responded to a report of a break-in. Police were also notified that an individual was experiencing a medical emergency, leading officers to believe it was the same person.

Police said that after finding Martin inside the residence, a brief struggle occurred. Once in custody, Martin became unresponsive. Paramedics arrived, attempted resuscitation on site, and transported him to a local hospital, where further efforts were made, but he later died.

The police officers involved in the incident were placed on paid administrative leave, as the OPD has started an investigation into the matter.

ESPN reported that the agency that represented Martin during his career, Athletes First, stated that his family claimed he was struggling with mental health issues before the incident, and they were seeking help for him.
