A serial groper may have struck again in Fairfax County, authorities said, and for the first time, the attack occurred in a commercial business with other people nearby.

About 3 p.m. Thursday, a 31-year-old woman was shopping in the HomeGoods store in Kingstowne Towne Center when a man who was following her grabbed her and then left the business. Several passersby tried to help track down the man, but he fled from the area, according to the Fairfax County Police Department.

The attacker was described as a Hispanic man who is about 30 years old. He was wearing a black jacket, light-colored pants and a black hat.

Police believe that Thursday's assault may be the 24th attack committed by one man in the Springfield area since September. Other gropings have taken place while the victims were walking or jogging outside.

Fairfax police spokeswoman Lucy Caldwell said that police hope the investigation will be aided by the fact that there were other people around during Thursday's attack.

"We're hoping that this will lead to additional information and hopefully an apprehension," Caldwell said.
