SAN ANTONIO – A Bexar County Precinct 1 deputy constable who was arrested on suspicion of driving drunk has resigned, the constable's office said.

Hieu Biu, 29, was arrested at approximately 12:44 a.m. Thursday on Interstate 35.

Biu was hired by the county in November 2018, a county public information officer said.

Biu was placed on administrative leave pending an internal investigation into the arrest. But since he resigned, the investigation will no longer be conducted, officials said.

The case will be forwarded to the Bexar County District Attorney's Office.
