A 15-year-old girl reported that she was grabbed from behind and fondled Tuesday night in Springfield, and police are investigating to see whether this assault and three others are related.

Tuesday's incident occurred in the 6200 block of Hibbling Avenue at about 7:15 p.m., when the girl was walking. After she was grabbed, she pulled away and fled, according to the Fairfax County Police Department.

Police spokeswoman Lucy Caldwell said that the attacker was a man, but no other description was available Wednesday morning.

The other three fondling cases took place last month, also in the Springfield area. In each of these similar incidents, the suspect wore a plain, red baseball cap.

In the first one, a 26-year-old woman was walking in the area of Old Keene Mill Road and Springfield Boulevard at about 8:30 a.m. on Sept. 7 when she heard a whistle, police officials said. She was grabbed from behind and fondled in the 7200 block of Monticello Boulevard, and she described her attacker as a Hispanic man about 5 feet 6 inches tall.

On Sept. 18 at about 2:45 p.m., a 16-year-old girl was walking on a path in the 6700 block of Metropolitan Center Drive when she was grabbed and fondled. The suspect, described as a Hispanic male with a thin, black goatee or beard, ran away after the attack. In addition to a baseball cap, he wore blue jeans and a white T-shirt.

At about 9 a.m. on Sept. 27, a 17-year-old girl walking on a sidewalk in the 5900 block of Erving Street was grabbed from behind and fondled, officials said. She described the suspect as an Asian or Hispanic man in his mid 30s, about 5 feet 8 inches tall, with a black, close-cut beard. In addition to a hat, he was wearing a blue T-shirt and black cotton sweatpants with a white stripe on each side.
