HOUSTON --Detectives are searching for four suspects who worked together to assault a smoke shop employee and steal gaming machines from the northwest Houston business. On Tuesday afternoon, two of the suspects walked into the smoke shop in the 18000 block of West Little York and started playing with the game machines inside the business, according to a Crime Stoppers statement. The men asked an employee for help, and as he tried to assist them, one of the suspects struck him on the head and body. The suspect stunned the employee with a stun gun then pointed a gun at him, threatening to shoot him if he didn't lie on the floor. While the second suspect served as a lookout, the two other suspects entered the store and used dollies to steal several game machines. The suspects arrived in a dark-colored Chevrolet Avalanche, but may have used a second vehicle, a box-type truck, to move the machines. The suspects are described as four Hispanic or white males, 20 to 30 years old. Anyone with information regarding their identities is asked to contact Crime Stoppers at 713-222-8477 (TIPS).
