The U.S. Postal Inspection Service is offering a reward for any information leading to an arrest in connection with the armed robbery of a San Antonio mail carrier. 

The robbery happened at 2:47 p.m. March 30 at 6513 Rosethorn Drive. 

The three unidentified suspects were described as wearing dark-colored face masks and dark-colored hoodies with sunglasses, according to USPIS. 

The suspects were armed with a handgun at the time of the robbery and should be considered “dangerous,” the agency said. 

The agency is willing to offer $150,000 to anyone with information leading to an arrest.  

USPIS also posted a photo and video of the car they believe belonged to the suspects, which is a silver, four-door Kia Optima.
