AMHERST -- A student arrested at gunpoint Tuesday after he allegedly caused a disturbance on the University of Massachusetts campus while dressed as the character "Rorshach" from the graphic novel series Watchmen was trying to get kicked out of school, police said.

The Daily Hampshire Gazette reports that Hejian Liu, 20, of Newton, was arrested shortly after 3 p.m. Tuesday between the Campus Center and the W.E.B. Du Bois Library.

Liu was allegedly dressed in the character Rorshach's signature garb, which includes a trench coat, fedora, and white facial mask dotted with inkblots. Campus police said callers reported that Liu was making obscene gestures at people and buildings.

“He was acting very odd and drew the attention of others,” Deputy Police Chief Patrick Archbald told the newspaper. “He concerned a number of people as he walked around.”

Archbald said that when officers responded and asked Liu to stop, he continued behaving oddly. After refusing to comply with the officers' orders, police wrestled Liu to the ground and placed him under arrest. The officers drew their service weapons during the arrest, Archbald said.

Liu faces a charge of disturbing the peace. Information about what disciplinary action he might face from the school was not immediately available.
