A D.C. policeman shot and wounded a 17-year-old girl last night when she allegedly lunged at the officer with a knife as he and other officers were attempting to arrest two men at a Northwest rooming house, police officials reported.

Officials said the girl was shot once in the right shoulder by Officer James Tarantella shortly before 9 p.m. inside 1009 O St. NW. The girl, who has been charged with assault on a police officer while armed, was listed in serious condition at Washington Hospital Center early today with a wound to the right shoulder.

Tarantella and three other officers, all assigned to the Morals Division, attempted to gain entry to the rooming house after a man had been seen dragging a woman inside, officials said. The officers were challenged at the doorway by a man whom they arrested after a brief scuffle, and then by a second man who threatened them with a knife, officials said.

As the second man was being arrested, officials said, the girl appeared and attempted to stab Tarantella, who fired one shot from his service revolver.

Police said Charles Jones, 22, was charged in the incident with assault on a police officer. His brother Renaldo, 18, was charged with assault on a police officer while armed. Both suspects are residents of the rooming house.
