Philadelphia Police are investigating cell phone video of a skateboarder's brutal attack on a park ranger.

According to police, the ranger saw several young men skateboarding in the city's Love Park, where skateboarding is prohibited, and approached them to tell them to leave.

Disturbing video of the incident taken by a bystander shows one of the young men wrestling the ranger to the ground and repeatedly punching, kicking and stomping him while the other young men taunt the ranger and videotape the attack.

Luckily, the victim did not suffer serious injuries, and the 19-year-old man behind the beating has been arrested and charged with aggravated assault.

The man reportedly told a local affiliate he got "caught up in the moment." Authorities are still looking for the other two suspects.
