SPRINGFIELD, Va. (CBSDC) — Police met with residents Thursday night to discuss the string of groping attacks in the Springfield area, the latest of which occurred Tuesday.

The community-wide meeting, which took place at Crestwood Elementary School, was designed for police to brief residents on the assaults and provide crime prevention strategies that may help women from being victimized.

Police said the simple assaults all have targeted females who are walking alone, and they usually occur around dawn or dusk on warmer days. The attacks have taken place around the greater Springfield area, and police believe the suspect or suspects know the area well enough to have escape routes planned.

Police also said they don’t know if there is more than one person responsible for the attacks, and added that they can’t pinpoint a specific age range or race for the suspect based on varying descriptions from different reports.

Tuesday’s incident, in which a 32-year-old woman was grabbed from behind while placing luggage into the trunk of her car in the 6400 block of Franconia Court at about 7 p.m., brings the number of possible related assaults to 22.
