He approaches his victims from behind and claims to have a gun.
There have been two robberies so far this month. Police say the suspect waits until a woman goes alone into the ATM vestibule. He is described as a black male between 5-foot-10 and 6-feet tall, 160 pounds with salt and pepper hair, glasses and a beard.
The first incident happened on September 3, when he targeted a Hispanic woman and demanded money, simulating that he had a gun. The second crime was on September 11, when a caucasian woman was robbed. The suspect reportedly poked an object in her side and claimed to have a gun. He took the woman's money and fled.
Police say in both cases, the victim was not injured. Anyone with information is asked to call police.
