In another incident, police arrested six protesters the night before

Washington (CNN) A 15-year-old girl was pepper sprayed and said she was groped Tuesday during a protest outside Donald Trump's rally in Janesville, Wisconsin, according to local police, one of several incidents at the event that required law enforcement.

The teenager said she was groped by a male in the crowd, then was pepper-sprayed by another individual after she pushed him away, according to a news release from the Janesville Police Department. A 19-year-old woman was also hit by second-hand pepper spray, police said.

Authorities are looking for one person in connection with the alleged sexual assault and another in connection with the pepper spray. Police released an image Wednesday of one individual in connection to the alleged incident, but they did not specify which alleged crime the person was possibly connected to.

Police also said that of the 1,000 attendees inside the event and 1,000 people outside, both supporting and protesting Trump, two people carried concealed weapons and two carried weapons openly, and all four cooperated with law enforcement.

Three suspicious objects were investigated, including a vehicle left in the street by someone who had gone to get food, but all were cleared.
