RALEIGH, N.C. — A number of dry cleaners were robbed last year in the Raleigh area. Police think it was all done by the same man who they say was aggressive and threatening to store employees.

Bob Hilker, owner of Brothers Cleaners, said the man hit two of his stores and attacked two employees.

"He came in about 6 o'clock in the morning, threw her on the floor, put a gun to her head, told her to open the safe and do everything he wanted," Hilker said.

As a result, Hilker has had to increase security at his stores.

"Everybody in our company was scared, frightened. We had to put in new lights. We had to change our hours of operation," he said.

After an in-depth investigation, police have taken a man into custody they think is responsible. They said the person was arrested Thursday as he tried to rob a bagel store in north Raleigh. Investigators then searched his Knightdale home and took away several items, including his trash.

People who work at the stores that were robbed are breathing easier.

"That makes me feel happy to know that he is off the streets. People can feel safe, safe in their job place," employee Sharon Shamblee said.

Police are still questioning the man and have not formally charged him, so they are not releasing his name. However, the man could face charges in connection with other robberies.
