(Corvallis, OR) -- Police say they've arrested a suspect in connection to a bomb threat involving food delivery robots at Oregon State University. The university took to social media just after noon yesterday to warn students and staff to avoid the robots in response to the threat. Campus Public Safety worked to locate the robots and isolate them in safe locations, where they were inspected and found to be free of bombs. The university declared the emergency over just after 1:30 p.m. The small robots can deliver food from campus restaurants to any outdoor location. They've been in use since 2020 and there are 20 delivery robots in the fleet.
