Dallas Police Chief U. Renee Hall fired two officers Thursday following investigations into criminal allegations, the department announced in a release.

Hall terminated Officer Christopher Hankins after he was arrested three times last year.

Police said an internal affairs investigation found he'd improperly worn a police raid jacket while off-duty and took grocery items from a Denton Walmart without paying for them.

Police said previously that Hankins had walked out of the store with $830 worth of groceries that he hadn't paid for.

Hankins was also arrested twice the following month — he was on administrative leave at the time — on family violence charges.

He had been hired in 2014 and was assigned to the north central patrol division, police said.

Officer Elvia Mercado was also terminated after an internal affairs investigation found she drove under the influence of alcohol. She was arrested in February after she was pulled over in Irving.

Mercado had worked for the Dallas Police Department since 2002. She was assigned to the north central patrol division.

The officers are allowed to appeal their terminations under civil service rules, police said.
