HOLIDAY LAKES, Texas (AP) — Investigators say a man suspected of attacking a South Texas police chief during a disturbance call has died in custody.

The Brazoria County Sheriff's Department says the death of 53-year-old Jimmy Lloyd Washington Jr. of Rosharon (roh-SHEH'-r'n) may involve delirium and use of a controlled substance. Autopsy results were pending Thursday.

Holiday Lakes police Chief Harold Douglas suffered bumps and bruises but didn't require medical attention.

Douglas on Tuesday night answered a possible home invasion call in Holiday Lakes, a town of about 1,100 located 40 miles south of Houston.

Investigators say some residents reported an unknown man pounding on doors. Authorities say Washington knocked the police chief to the ground and the pair struggled.

Some residents helped subdue Washington, who became unresponsive while handcuffed. He died at a hospital.
