A handcuffed Florida man in police custody drowned on Sunday after he broke free from an officer and jumped into the Boca Ciega Bay, according to authorities.

Donnie Brownlow Jr., 33, had been arrested by police who responded Sunday evening to reports of a domestic disturbance in Treasure Island, which is near Tampa Bay.

Brownlow was arrested for domestic battery, obstruction, felony driving while license suspended or revoked, and violation of probation. He was then taken to the Treasure Island Police Department to wait for a jail transport van.

"Detectives say while being escorted to the transport van and in handcuffs, Brownlow broke free from the officer, ran toward Boca Ciega Bay and jumped into the water," according to a news release by the Pinellas County Sheriff's Office.

Paramedics would pull Brownlow from the water and performed CPR, deputies said. He was then transported to a local area hospital where he was pronounced dead around 9:40 p.m.

The Medical Examiner’s Office will conduct an autopsy, although the sheriff's office said his death does not appear to be suspicious in nature. An investigation is ongoing.
