Before a Donald Trump rally in Wisconsin on Tuesday, a 15-year-old girl was groped and then pepper-sprayed, according to police.

Hundreds of anti-Trump protesters gathered outside of a Holiday Inn Express before Trump's speech, USA Today reports.

"A male in the crowd groped the 15-year-girl; when she pushed him away, another person in the [crowd] sprayed her," the police department said in a statement obtained by the outlet. "We are currently looking for two suspects, one for the sexual assault and one for the pepper spray."

In video footage posted on YouTube, the girl says to a man, "You were touching my breasts," and he responds, "You touched me. I never touched you." As the crowd circles around them, she shoves or punches the man, and someone immediately pepper-sprays her in the face. Then, the crowd begins to cheer and clap.

Police said the teen received medical treatment.

The incident is the latest in a string of violence at the GOP front-runner's rallies. Earlier this month, Trump canceled a rally in Chicago out of safety concerns. And Trump's own campaign manager was charged with simple battery this week after a run-in with a reporter.
