PROPHETSTOWN – A Prophetstown High School special needs student spoke to others about causing violence today, but after an investigation, police say the school is safe.

In a lunchtime conversation Tuesday, the boy told other students about his plan for violence, Chief Michael Fisk said Thursday. They immediately disclosed the conversation to school officials, who called police, he said.

Fisk wouldn’t reveal the nature of the threat, but he said the police have determined the boy had no access to weapons.
