SAN ANTONIO -

The San Antonio Police Department is asking for the public's help in finding a man wanted for a robbery that occurred in February.

The incident happened around 7 p.m. on Feb. 10 at North Frio Street and West Commerce Street.

After arriving at the store, police met with Troy Dietrich who said he was looking for a ride to cash his check when the suspect offered to help him find one.

The two contacted another person who was driving a vehicle that Dietrich could only describe as a silver or white car. He gave police two possible license plate numbers, which police said neither were registered.

The three drove to Zarzamora Street and Southwest Military Drive. Dietrich told police that it appeared that the suspect knew the driver of the car.

Dietrich walked into HEB to cash his check and shortly after, the suspect went into the location to wait on him. Dietrich said it felt like the suspect was standing over him.

After Dietrich cashed his check, police said the driver of the vehicle returned him and the suspect to where they were. Dietrich gave the driver $20 for the ride, and he and the suspect began walking west from the area.

When they got around the corner and were in the dark, police said the suspect punched Dietrich in the face. Dietrich told police that he was knocked to the ground and was dazed. He felt the suspect reach into his back pocket and pull out his wallet. Cash was then taken out of the wallet, in which police said the suspect threw back at Dietrich and fled with the cash.

Dietrich said he saw the suspect get into the vehicle, which drove away from the location. Dietrich could not describe the vehicle because police said he was still stunned from the hit.

San Antonio police described the suspect as a black man who is 30 to 35 years old, approximately 5 foot 10 inches tall and weighs about 170 pounds. The suspect has black hair and brown eyes, and police said he wore a black long-sleeved shirt and blue pants at the time of the robbery.

Those with information regarding the suspect's identity or his whereabouts are asked to call Crime Stoppers at 224-STOP. Crime Stoppers said it will pay up to $5,000 for information that leads to the arrest of those responsible for this robbery.
