Four teenagers have been arrested after a series of flash mob style attacks around Temple University campus in which students were beaten by gangs of juveniles.
Police said that in a spate of attacks on Friday night, students were surrounded, then punched, kicked, robbed and in some cases knocked to the ground by groups of teens.
Groups of between 20 and 100 young people roved the university campus in northern Philadelphia for nearly two hours from 8pm and picked on people at random.
Six students were injured and a university police officer who was knocked to the ground. A police horse was punched in the face by a 15-year-old boy.
In a separate incident a young woman was held down and stomped repeatedly before employees from a nearby pizza place intervened, her father said.
Another junior posted pictures of her black eye. She says the attackers punched her in the face as she walked back to her apartment with her boyfriend.
Temple spokesman Ray Betzner told television station NBC 10 that the mobs of teenagers played a 'cat-and-mouse game' with police.

Temple campus safety director Charles Leone told television station WPVI that it appears victims were picked at random and that students were not targeted.
But he said, 'It's very concerning that you can get a group of juveniles to pull together that quickly and some become violent.'
He said the university and city police will be stepping up patrols through the rest of the semester, especially because next weekend is Halloween.
Temple serves about 34,000 full-time students.
The violence broke out after about 200 juveniles, apparently responding to social media posts, converged outside an off-campus movie theater, Temple police said in a report to the university community.
For the next few hours, they said, the juveniles split into smaller groups, some of which assaulted people they encountered as they ran from police.
