Stony Brook University officials say an investigation has been launched into the emergence of anti-Muslim posters on campus.

Students say the posters first started popping up on bulletin boards Wednesday morning. College officials say 12 fliers have been found and pulled down, but they would not describe them in detail.

Several students say one of the posters was a replica of the cartoon published in a Danish newspaper that sparked violent protests around the world years ago. It depicted Muhammad with a bomb on his turban.

A number of Muslim students say they?ve never experienced any hostility on campus.
