An Eastern Kentucky University student was arrested for allegedly posting a threatening note on a refrigerator wrapped in duct tape.

EKU Police charged Jacob Walker with first-degree terroristic threatening, a class C felony, the university said in a news release. Walker, 18, is a first-semester freshman and residence of Palmer Hall, where the device was found by resident hall staff.

The device was a mini-refrigerator wrapped in duct tape, EKU spokesman Marc Whitt said. Whitt said he could not elaborate on what the note said.

"However, it was serious enough that it led the residence hall staff of Palmer to evacuate the residents of that dorm," he said.

EKU police and state police investigated the refrigerator, which "was dressed in a way that could have resembled an explosive device," Whitt said.

Students were allowed to return to the residence hall when officers determined the device was not dangerous. About 240 male and female students live in the dorm.
