A 19-year-old teen who allegedly beat up a Philadelphia park ranger who asked him and his friends to stop skateboarding was turned into police by his own mother.



Curtis Tanner, of Pottstown, Pennsylvania, was arrested Tuesday after a video of the awful attack surfaced on YouTube on Saturday, showing the ranger being tackled to the ground and repeatedly kicked and punched.



Police were able to identify Tanner from the video - as well as a 17-year-old suspect - and went to his house yesterday, but he was not home.



When he returned, his mother called police, who came back to the house and arrested Tanner, according to Philly.com.
