A two-hour bomb scare ended late Thursday morning at a Southern California hospital after no explosives were found on a man who walked into the emergency room claiming to have a bomb.

Emergency room staff at Loma Linda University Medical Center could see exposed wires on the man, so they used a portable x-ray machine to scan the device and determined it looked like a bomb, the Riverside, Calif. Press-Enterprise reported. It was not clear where on the man's body the device was located.

The local bomb squad took the man and the device to a hospital parking garage to conduct their own examination, the newspaper reported. When no explosives were found, sheriff's deputies lifted the blockade around the emergency room.

The man, described as a Hispanic adult in his 50s, was taken for a psychiatric evaluation.

Loma Linda is approximately 60 miles east of Los Angeles.
