Charleston police are looking for a man with a tattooed left arm who is wanted on charges that he pulled out a gun Sunday during an encounter in Marion Square.

Investigators on Tuesday released surveillance images showing a possible suspect 10 minutes before the alleged gun incident.

The photos depicted a white or possibly Hispanic man who stands about 5 feet, 8 inches tall and has a left arm with several tattoos, according to the Charleston Police Department. At the time, the man was wearing black clothes and a bandana on his head.

Minutes later, the police said they think the same man approach two people in the downtown square at King and Calhoun streets and asked them for money.

When the two people told him that they didn't have any cash, the man pulled out a gun and "yelled profanities" while pointing it at them, the police said.

The alleged victims took cover, and the man ran across the square toward Meeting Street, the police said in a statement.

Detectives want members of the public to take special note of the possible suspect's tattoos in the surveillance footage and contact them with any information about who the man might be.

Call dispatchers at 843-743-7200 and ask for the on-call Charleston detective or Crime Stoppers at 843-554-1111.
