Three male friends two from Fort Washington and one from Oxon Hill were also cut in the incident, according to Officer Henry Tippett, a spokesman for the Prince George's County Police Department. None of the injuries were life-threatening.
The incident took place around 1:30 a.m. outside an unidentified auto body shop in the 6300 block of Old Branch Avenue where the party was taking place.
Prince George's police are searching for two suspects, whose identities are unknown.
Police still do not know whether the victims knew their attackers, or what events led to the stabbing, Tippett said.
