It started at a Crofton Bank of America on Davidsonville Road in the middle of November.
A woman alerted police two men tried robbing her in the parking lot at gunpoint.
"Something startled the suspect under these circumstances. He fled and shortly thereafter, about 25 minutes later, a 7-Eleven on 450 was robbed at gunpoint," Marc Limansky, a spokesman with the Anne Arundel County Police Department, said.
The men demanded money and then took off with a fistful of dollars.
Then on the very next night -- the two struck again at the same store.
"At about the same time, at about 11 p.m., another robbery occurred at that 7-Eleven. So our officers began investigating. Detectives were investigating which led them to the identity of these two suspects," Limansky said.
The convenience store has been a frequent target for thieves.
In October, crooks rammed a pickup truck into the store looking to get a quick grab.
Without knowing for sure if the three robberies are connected or if this particular store is just unlucky, the two young robbers tried to, says Limansky, go on a spree.
"They had a plan and they realized what had worked the previous evening. They tried it again the previous evening, but thanks to the diligence of our investigators, they were about to track down these suspects and make the arrests," Limansky said.
Both men have been charged with armed robbery and weapons charges and are being held without bond.
