Two men, one armed with a handgun, robbed a Jessup bank of an undetermined amount of cash Thursday afternoon but dropped the bag of money when a dye pack exploded, Howard County police said.
No one was injured during the robbery, which occurred shortly after noon at the Signet Bank in the 8600 block of Washington Blvd., police said.
The two men entered the bank, demanding money from the tellers.
One robber vaulted the counter as the other stood in the lobby with the handgun.
The robber who vaulted the counter ordered the four tellers to empty their cash in a bag, police said.
After getting the money, the robbers ran outside, but the dye pack exploded before they left the parking lot.
The robbers dropped the bag and drove south on Route 1 in a black or gray Audi, police said.
A bank audit will determine if all the stolen cash was recovered on the lot, police said.
The armed robber is described as between 20 and 30, 5 feet 7 to 5 feet 9 inches tall.
He was wearing a dark-colored hat and holding a cloth over his face during the robbery, police said.
The second robber is described as between 5 foot 9 and 5 foot 10 inches tall, police said.
He was wearing a ski mask.
