The FBI said the serial robbers entered the bank armed with pistols and wearing masks to conceal their faces. They ordered all employees to the ground.

One robber waited in the lobby and stood watch with his weapon over the employees, while the other went behind the counter and stole an undisclosed amount of cash from a teller drawer.

The armed robbers left the bank in a silver Hyundai Elantra. Investigators later recovered the vehicle near the bank and determined it had been reported stolen a month ago.

No one was physically hurt during the robbery.

Investigators believe the armed duo are also responsible for two other Houston bank robberies – the robbery of the Wallis State Bank located at 10055 Almeda Genoa on April 5, and the robbery of the Mercantil Bank located at 3200 South Shepherd on April 3.

The robbers got away with an undisclosed amount of cash in both robberies. The robbers fired gun shots during the robbery of the Wallis State Bank, but no one was seriously hurt.

The bank robbers are described as black males in their twenties, both about 5 feet 9 inches to 5 feet 11 inches tall with a medium build.

Crime Stoppers of Houston is offering up to $5,000 for information leading to the identification and arrest of these serial bank robbers.
