The FBI needs the public's help finding several men believed to be responsible for eight similar robberies in the metroplex over the past year.
Police said the robberies have been getting increasingly aggressive. In each case, the suspects enter the bank armed with weapons and get away with an undisclosed amount of cash.
They have hit banks from Flower Mound to Plano to Dallas and cities in between.
Police said usually two to three men will rob the bank with their faces covered and dressed in black.
They always have a stolen car to get away in, which is later found abandoned not far from the bank.
While the robberies are very similar, police say there is a possibility they are not all connected.
The most recent robbery occurred June 17 at ViewPoint Bank in Grapevine.
No one has been seriously injured in any of the robberies, but investigators are concerned about the increasingly aggressive nature of the crimes.
The robbers are described as black men in their late 20s or early 30s, ranging from 5-foot-7-inches to 6-feet tall. Two of the men have a thin build and one is heavy-set, police said.
In each case, the men have worn long pants, long-sleeved shirts, gloves, hoodies or baseball-style hats and full masks or bandannas covering their faces.
