Singer Jennifer Lopez and producer Sean “Puffy” Combs were questioned by investigators early this morning after they witnessed a shooting at Club NY, a Times Square-area nightclub. Neither Lopez nor Combs were injured, but two men and a woman suffered minor injuries to their faces and shoulders. Lopez and Combs were at the midtown Manhattan club when gunfire erupted about 2:20 a.m., said a police spokeswoman. A 19-year-old man was arrested on weapons charges. Two others are also being questioned about the incident. Some news reports are saying that Combs had a concealed weapon in his vehicle, but that police have not arrested him.
