Tonight the American teenager caught up on the violence is back with his parents after his beating at the hands of Israeli police officers. Alex Marquardt is in Jerusalem with the latest. Reporter: Walking free. 15-year-old American Tariq Abu khdeir leaving a Jerusalem court today after being held for three days without charges following the vicious beating by police seen here. Repeatedly kicked and pummeled as he was pinned to the ground. We were there as Tariq arrived home still bruised and swollen and angry. What would you say to the Israeli police officers? If you could speak to them now? I would say why would you attack me like that. Tell me why would you do that to me if I didn't do anything to you? Reporter: Israel's ambassador to the U.S. Told ABC's Martha Raddatz today that during clashes with the police Thursday Tariq and five others attacked the police with molotov cocktails. Our police are under extreme threat in the Jerusalem area. Facing monsters and riders. Doesn't mean that excessive force is acceptable. Reporter: Tariq says he was watching the protests. Tonight we visited his uncle's home where Tariq is under house arrest. His mother telling she's she leaved his safe but outraged no one has been held responsible. No child should be put through this. He's 15 years old and had three guys on him beating him half to death. Reporter: Those clashes follow the murder of his cousin abducted and burned alive last week. Today the police arrested six young jewish men, two of whom are believed to be on the tape suspected of carrying out the murder. Attack by extremists for the recent killing of three Israeli teens. Tonight there's a growing fear if these types of revenge attacks from either side could trigger a new conflict. Elizabeth. Turning now to a different kind of fire storm.
