Philadelphia's police commissioner says he's been rebuffed in his efforts to investigate claims that a teen suffered a groin injury during a police stop.

Police Commissioner Charles Ramsey says no official complaints have been filed, and neither the teen nor his lawyer are speaking to authorities.

Lawyer Lewis Small says 16-year-old Darrin Manning and his teammates were walking to an after-school basketball game last month when police approached.

He says Manning needed groin surgery after being injured during a pat-down by a female officer.

Manning has been charged with several misdemeanors, including resisting arrest.

Small says he will not allow Manning to speak to police while the charges are pending.

The Associated Press normally does not name suspects charged as juveniles, but Manning's family allowed the use of his name.
