What happened in Dupont Circle yesterday? Was there a bomb threat that caused the U.S. Park Police to clear the park? According to a participant of the 16th Annual Pride of Pets dog show, the park was cleared for about 30 minutes during the event.

Another eyewitness reported that around 4:30 p.m., the Park Police suddenly blocked off streets leading to Dupont Circle and then forced everyone to leave:

“Moments ago, US Park Police cleared Dupont Circle of all persons, announcing the move was ‘for everyone’s safety.’ Meanwhile, DCMPD and Fire/EMS had a heavy presence in front of the CVS, including no passage for pedestrians or vehicles. I don’t see anything on the news or blogs yet.”

Anyone know anything?
