According to the Harris County Sheriff's Office, an armed duo robbed a Valero gas station in the 8000 block of North Sam Houston Parkway in northeast Harris County around 10:50pm Friday.
A Houston Police Department officer saw the suspects leaving and followed their vehicle, an HPD spokesperson said.
A suspect opened fire on the officer during the course of the brief pursuit, officials said. He suffered a minor facial injury and was treated at the scene and released.
The suspects got away and investigators are searching for them. HCSO officials said they were in a silver Chevrolet Malibu with Mississippi license plate number LWE602.
Police are reviewing surveillance video to identify them.
