CHAPEL HILL - UNC Chancellor Holden Thorp shut down a campus anti-immigration group Friday after an anonymous flier targeted its faculty adviser, who then joked about his skills with a Colt .45.

Activists put out the flier last week revealing the home address of Youth for Western Civilization faculty adviser Elliot Cramer.

Chapter President Nikhil Patel informed Cramer about the flier.

"Thanks for your concern," Cramer replied just after midnight, copying Thorp. "I have a Colt .45, and I know how to use it."

Cramer said that he didn't consider the flier a real threat and that his response to Patel was "light-hearted." He complied with Thorp's request to resign.
