Daniel Grant, 29, of the 4200 block of Dunwood Terrace in Burtonsville, was arrested Monday about 12:30 a.m. while trying to leave the store, which had closed several hours earlier, police said.
According to police, Grant entered the store in the White Oak Shopping Center on New Hampshire Avenue before it closed Dec. 4, posing as a customer. He then hid in the store until it closed.
Once employees left, Grant allegedly pried open cash registers and took an undisclosed amount of cash.
Police responded to the store after an alarm was activated, and Grant was caught on video roaming the Sears basement.
Grant has been charged with second-degree burglary and theft of less that $1,000 value, and remains in custody on a $100,000 bond.
Police said that Grant will also be charged with the Nov. 23 burglary at the Sears store in Lakeforest Mall on Russell Avenue.
Investigators believe Grant might also be connected to a third burglary a Sears store in Columbia last weekend.
