HOUSTON (KTRK) --Police are investigating after an off-duty Harris County Sheriff's deputy opened fire during an attempted robbery in northwest Houston.
Houston police say the attempted robbery happened around 10pm at a convenience store on West 43rd Street near Rosslyn Road.
The off-duty deputy was patrolling the store as one of several locations he guards when he stopped to speak with the store clerk.
Investigators say at one point, two black men wearing masks and armed with guns entered the store.
Police say the deputy drew his weapon and that is when both suspects pulled out their guns, pointing the pistols at the deputy.
The deputy opened fire on the suspects, but police do not believe they were injured.
Officers say the deputy also opened fire in the parking lot of the convenience store, but both of the suspects in that attempted robbery were able to flee the scene on foot.
Investigators say both men were able to run to a getaway vehicle on Nina Lee Lane the next block over. The suspects are still at large.
Detectives are looking through surveillance footage in hopes of finding more details about the suspects.
