Mayor Luke Ravenstahl said he is "very troubled" by claims that a Homewood high school student was beaten by undercover police.

Jordan Miles, 18, was treated at a hospital twice after an arrest last week by three plainclothes Pittsburgh police officers. Police suspected he had a concealed gun and -- after a chase and a struggle with the Creative and Performing Arts High School senior -- concluded he was holding a bottle of Mountain Dew instead. He was charged with aggravated assault and resisting arrest, but when officers did not show for a court hearing Thursday, the matter was postponed.

Mr. Miles took several blows to the head and face, was Tasered and had a chunk of hair ripped from his head, his lawyer said. He was walking between homes owned by his mother and grandmother when police stopped him.

Police claimed that they identified themselves to Mr. Miles and repeatedly tried to subdue the 18 year old after he fled.
