From NBC4:

Authorities in Athens said that they were investigating a mountain bike that put the Ohio University campus on high alert Thursday morning.

Athens Acting Fire Chief Ken Gilbraith said that the bike had a sticker on it that said, “This bike is a pipe bomb.” He said the university police discovered it overnight, parked outside a campus restaurant.

OU closed four buildings, police blocked streets around the Oasis restaurant, the fire department brought in off-duty firefighters, and the Columbus fire department’s bomb squad was called in.

Gilbraith said the bomb experts attacked the bike with a high-pressure spray of water, then pried it open with a hydraulic tool and found no bomb inside.
