U.S. Park Police arrested a man lurking suspiciously overnight in Arlington National Cemetery and closed several major roads near the Pentagon Friday morning.
According to WRC-TV, an explosive device was found in the man’s vehicle parked near the Pentagon, though a Park Police spokesman said he could not confirm that. According to WJLA, the man may have had ammonium nitrate on him when arrested.
