MADISON, Wis. -

A teenager said she was attacked and beaten by three classmates near East High School.

Two 16-year-old girls and a 15-year-old girl were arrested last week in connection with the assault.

The victim, Alana Krupp, 15, said she knows the girls involved but maintains she wasn't talking trash about them.

The incident happened last Wednesday at the intersection of Fourth Street and Winnebago Street a block south of East High School.

Krupp arrived at the bus stop like any other day, but in a few seconds an otherwise OK freshman year at East High School was turned upside down when she was confronted by the girls.

"She said, 'I wanted to fight you.' And I said, 'I'm not going to fight you, because there's no point in it. I never did anything to you,'" Krupp said. "She hit me in the face, and I got pulled down to the ground by my hair."

Krupp said she was repeatedly punched and kicked in the head. She said she was thrown to the ground and basically unable to defend herself during the attack.

She said she doesn't think the attack would have happened on the school campus, but just a block away from school no one, including her classmates, stepped in to stop it.

"I couldn't really talk, because they were hitting my face, and I didn't even know what to say. I think I said stop once or twice, but there wasn't much I could do. They weren't going to stop," Krupp said.

Police said the girls recorded the attack and posted the video to Facebook. The video has since been removed.

"It wasn't really until that afternoon when the police officer called me (and told me) that there was a video, that these girls were really vicious," said Sarah Krupp, the victim's mother.

Sarah Krupp hasn't seen the video, but police have. On the video clip, one of the girls said, "It don't matter if you want to fight or not ... she gonna hit you," according to Madison police.

"It's scary. You send your kids to school to learn and to learn lessons from school, not to learn these kinds of lessons that people are just going to watch you get beat up and not going to help you," said Sarah Krupp.

Alana Krupp said her bruises have healed but she is still emotionally scarred by the incident.

As for the school, a district representative said that when incidents happen off campus, the district works with the police and sometimes set up a student safety plan after the fact. The district said it couldn't comment specifically on this case.

Alana Krupp has another meeting scheduled with the school.

Her mom said she heard girls on the bus threatening her daughter and emailed the school. Last Tuesday, school officials met with Alana and another girl and everything seemed OK but by Wednesday that had changed.

The three girls arrested face different charges. One was arrested on a battery charge, another on a charge of disorderly conduct and a third on a charge of being party to a crime.
