Deputies and bomb investigators from the San Bernardino Sheriff’s Department are at the hospital and have detained a suspect, who was described as being in his 50s, sheriff’s spokeswoman Cindy Bachman said.
Officials confirmed there was a “suspicious device” attached to a man's body but have not determined if it is explosive, Bachman said.
Authorities said they have moved the man from the entrance of the emergency room to an "enclosed concrete area" on the hospital's property as the investigation continues.
Hospital officials called the Sheriff’s Department after the man walked in about 9:20 a.m., Bachman said.
Bachman said the lobby was partially evacuated and traffic was shut down inside and outside of the emergency room, although the front entrance of the hospital remained open.
