Police in Texas are looking to question a man who was seen on surveillance video shooting and killing an armed suspect attempting to rob a Houston taqueria. 

Houston police are asking for the public’s help to find a man who was seen on video inside Ranchito #4 Taqueria in southwest Houston, shooting and killing an armed robber after the suspect entered the store and demanded valuables from customers at gunpoint.

In a Friday press release, Houston police say charges have not been filed against the man who fled but police want to speak to him about "his role in the shooting."

The video and witness reports show the suspect, who police say was in his 20s, wearing a black ski mask entering the restaurant and pointing his pistol at patrons and demanding their money.

Anyone with knowledge of the armed customer's identity is being asked to call Houston police homicide at 713-308-3600.

A spokesperson for the Houston Police Department told Fox News Digital that the armed customer, who was described as a "person of interest," has not yet been contacted as of Saturday afternoon.

"The person he shot was in the process of committing robbery and consequently his use of force in defense of himself and innocent third parties is completely justified in Texas," former Houston police officer, now lawyer, Thomas Nixon told KPRC-TV. "He was reasonably in fear of serious bodily injury or death."
