The Sheraton National hotel on S. Orme Street has been evacuated due to a reported bomb threat.

The threat was non-specific and phoned in to the hotel, we hear. Police have shut down S. Orme Street between Columbia Pike and Southgate Road (the entrance to the Marine Corps’ Henderson Hall) as a precaution.

The bomb threat was called in to the hotel on the first day of the Human Capital Management Defense conference. Dozens of attendees of a conference at the hotel have been evacuated. Scheduled speakers at the conference include a number of Department of Defense and U.S. government officials.

An Arlington County Police Department bomb-sniffing dog is on scene to assist with a search for any type of explosive device. ACPD is being assisted by Pentagon Police and Virginia State Police.
