TEXAS CITY, Texas (KTRK) -- An investigation is underway after a suspect was shot by an off-duty officer in Texas City on Friday evening, according to the Texas City Police Department.

The shooting happened outside a Buc-ee's gas station near the Gulf Freeway and Holland Road parking lot at around 10:35 p.m.

Texas City Chief of Police Landis Cravens said the officer was working a second job at the convenience store and attempted to detain a person suspected of shoplifting.

Police said the person in question began resisting the officer, which started a fight between the two.

The off-duty officer then tried other methods, such as a stun gun, to get the person under control before taking out his gun and opening fire, Cravens said.
