Janesville police have asked for public help to identify a man suspected of pepper spraying a protester outside Republican presidential front-runner Donald Trump’s campaign rally Tuesday.

Police released two photos Wednesday of a young man wearing glasses and a hat featuring the Trump’s signature “Make America Great Again” slogan. Detective Chris Buescher said the man is suspected of pepper spraying a 15-year-old girl after she punched another man during an argument.

The altercation was one of a few tense moments between the estimated 2,000 supporters and opponents of Trump at the rally at the Janesville Conference Center at the Holiday Inn Express.

The girl, whose face was covered with pepper spray, as she left the hotel grounds,was there to protest Trump and argued with a supporter.

Buescher said police have identified the girl who was sprayed, but declined to release the girl’s name because she is a minor.
