Jahmair Melville was taken into custody Oct. 25

Dover police have arrested a man thought to be the knife-wielding robber who tried to hold up a local store clerk.

Jahmair Melville, 18, was arrested without incident Wednesday, Oct. 25, department spokesman Master Cpl. Mark Hoffman said in a press release.

Police determined Melville was the suspect after following up on several leads, Hoffman said.

The incident took place at about 8:57 p.m. Monday, Oct. 23 at the Dollar Tree store at 261 N. Dupont Highway.

The clerk said a man came in and she told him the store would be closing at 9 p.m. Two other men came in, talked with the first man and then left.

At about 9:04, the clerk found the man in an aisle and told him the business was closed. The man pulled the knife and demanded money as he walked toward her while she went to the cash registers. The suspect grabbed the clerk by the shirt after she refused to hand over any cash, Hoffman said.

The woman lost her cell phone as she fell to the floor, but the would-be robber picked it up and demanded to be let out. He then ran away.

The clerk suffered some minor scrapes around her neck when the suspect grabbed her shirt, but she declined treatment.

Melville is being held on a $47,500 secured bond at the Vaughn Correctional Center, Smyrna, on charges of first-degree robbery, possession of a deadly weapon during the commission of a felony, second-degree assault and wearing a disguise during the commission of a felony.
