A deputy constable escaped safely from his patrol unit after it caught on fire while he was assisting a crash on Interstate 10 West, according to Precinct 4 Bexar County Constable Kathryn Brown.

Deputy constables responded to the crash Friday afternoon on I-10 between Foster Road and Ackerman Road, Brown said.

Among the group of deputy constables was "Deputy Day." Brown said he was typing information into a computer-aided dispatch system inside his patrol unit.
