British singer Lily Allen was arrested in London yesterday on charges of punching a paparazzo. The incident allegedly happened in March, when Allen is accused of punching the photographer as she left a London nightclub with her boyfriend. "At approximately 1:30 a.m. on the 13th March a woman allegedly punched a male photographer in his 40s, near the Wardour Club, W1," a Metropolitan Police spokesperson said. "He suffered a cut to the nose, but didn't require any hospital treatment. Officers attended but the woman had left." Allen turned herself into the police yesterday, where she was photographed and had her fingerprints and a DNA sample taken. "At approximately 9:30 a.m. on the 28th June, a 21-year-old woman attended at London police station by appointment and was arrested in connection with the allegation of assault," said the police rep. "She has been bailed to return in late July."
