Two teenagers are charged in a brutal attack at an iconic Philadelphia park that was caught on camera.

Two of the three skateboarders police say were involved in the beating of a 35-year-old ranger at LOVE Park, captured on cell phone video, have been arrested, police officials announced Monday.

Cell phone video shows a skateboarder violently attack a park ranger in LOVE Park Friday afternoon.

Curtis Tanner, 19, of Pottstown, was arrested at his mother's home. He's charged with aggravated assault, simple assault, recklessly endangering another person and making terroristic threats.

Police say Tanner was the one who attacked the park ranger. According to court records, Tanner is currently on probation for a 2013 robbery conviction. He also pleaded guilty to disorderly conduct after a fight a few months ago.

A Pottstown 17-year-old boy and junior at Pottstown High School is also charged as a juvenile with aggravated assault, simple assault and reckless endangerment. Police say the teen and his mother arrived at Central Detectives Monday afternoon.

Police are still searching for a third teen shown in the video.

Video of Friday's attack shows a teen kicking the ranger in the head repeatedly and spitting on him after he asked that they stop skateboarding in the park on 15th Street and John F. Kennedy Boulevard.

"Basically, he was just doing his job," witness Mariano Verrico of Essex Fells, New Jersey, who recorded the violent beating, said of the ranger.

The video shows the teens finally walk away when a man who appears to be dressed as Jesus walks towards them.

Verrico tells NBC10 he was too scared to try and stop the attack because he was outnumbered. He did escort the victim to a nearby police station and turned over his video.

The ranger suffered head injuries but is expected to make a full recovery, according to investigators. A skateboarding ban has been enforced at the iconic park since 2002.
