Updated 11 a.m. EDT | Authorities found no evidence of a shooting at the Washington, D.C., Navy Yard on Thursday. Someone had reported shots fired in the same building as a shooting rampage in 2013.
Police have ordered workers at the Navy Yard in southeastern Washington, D.C., to “shelter in place” as they investigate an unspecified incident Thursday morning.
A federal official, speaking on condition of anonymity, said there were reports of shots fired, according to the Associated Press.
The site is the same as where a gunman killed 12 people two years ago. The official said there are no reports of injuries nor has a shooter been identified. There were dozens of police cars at the scene and a helicopter flying overhead.
U.S. Capitol Police said they were monitoring the situation and there was no known threat to the Capitol Complex.
In September 2013, military contractor Aaron Alexis killed 12 civilian workers at the Navy Yard’s Building 197 before he was fatally shot by police. The building, since renamed the Humphreys Building, reopened this year.
