25-year-old Keith Lamar Thomas was arrested yesterday, October 2, 2019, and charged with two counts of aggravated robbery and one count of aggravated assault of a police officer following an extensive investigation by the Houston Police Department and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).

ORIGINAL [Oct. 16] — A Harris County Precinct 5 Constable's Office deputy was shot during a robbery while working an off-duty security job in northwest Houston on Wednesday night.

Around 8:25 p.m., the Houston Police Department was dispatched to an officer-assist call at the Five Guys restaurant in the 2900 block of North Shepherd where the deputy was working security.

According to the Houston Police Department, during a press conference on Wednesday night, the deputy constable observed a black male wearing a ski mask and carrying a semi-automatic handgun enter the restaurant and rob the store and its customers.

Police say the deputy was waiting for the suspect to exit the restaurant, due the presence of customers in the restaurant, when the suspect observed the deputy outside and opened fire through the restaurant's windows — striking the deputy constable at least once, possibly twice.

The suspect, described by police as a black male approximately 6'0"-6'3" and wearing a green and white sweat suit, fled the restaurant. Witnesses described a white Dodge Charger with black rims flee the scene of the robbery at a high rate of speed with its headlights off.

At last check, the deputy was described as being in stable condition and alert, undergoing surgery at Memorial Hermann Hospital in Houston. The 39-year-old deputy, who has not been identified, has 15 years of law enforcement experience and has been with the Precinct 5 Constable's Office for 12 years.

Police say the deputy was placed in a tough position because he couldn't shoot into the building, or return fire, due to the presence of civilians. It is believed the deputy did not fire his weapon.

A citizen came to the deputy's aid until paramedics arrived, according to police.

The robbery suspect remains at-large and should be considered armed and dangerous. Anyone with information is asked to call 911, Houston Crime Stoppers, or the Houston Police Department's Robbery Unit.
