Man robs gas station with screwdriver

League City police are seeking a man who robbed a gas station early Wednesday morning with a screwdriver.
League City Police Sgt. John Jordan gave the following account of the holdup:
At 3:47 a.m., the suspect entered a Valero at 1809 W. FM 646. He offered to use his debit card to pay for a Dr. Pepper for a customer already inside in exchange for $2. The customer agreed, but the suspect had to return the $2 when his debit card was declined, and both men left.
The suspect returned, however, at 3:51 a.m. and asked an employee if he could use the phone. The employee directed him to the phone outside and started to walk behind the counter.
The suspect followed the employee behind the counter and pulled out a large screwdriver. He told the employee to give him all the money or he would stab him with the screwdriver.
The employee handed over $150 to $200.
The robber fled at 3:52 a.m., and a surveillance camera showed that he left in a maroon, extended cab pickup.
The video did not capture the vehicle's license plate, but another camera inside the station did record footage of the robber.
The robber is a 5-foot-6 to 5-foot-7 white man who weighs 170 to 190 pounds and is 22 to 30 years old. He had on a white polo shirt, blue jeans, and a black and brown cap.
Anyone with information about the robbery is asked to call 281-338-8207.
