A shirtless man with a mohawk allegedly threatened to cut a 12-year-old girl with a knife unless she handed over her money, according to Dunwoody Police.

The armed robbery incident occurred June 15 about 6 p.m. at the intersection of Withmere Way and Withmere Lane. The victim told police that a black male suspect with a mohawk, age 16 to 18, and wearing gray pants with no shirt, got out of a gold, older model van and grabbed her near the intersection. The suspect allegedly threatened to cut the girl with a knife unless she gave him her money, police said.

The girl handed over the $40 she had and was not injured.

The suspect is also described as being 5-feet 8-inches to 5-feet 9-inches tall, weighing between 170 to 180 pounds, wearing black Nike sandals and with a one-inch scar on his jawline.
