Back-to-back shootings caused alarm for the Anacostia neighborhood in Washington, D.C. on Wednesday.
About 11:50 a.m., a bullet flew through a window at the U.S. Park Police Anacostia Operations Facility, putting the building on heightened alert.
Police said the shot appeared to have been fired from the nearby Anacostia Metro station parking garage.
"All the officers here on the scene responded as if we had somebody shooting at the building. We set up security. We sheltered in place," said U.S. Park Police Capt. Michael Libby.
No shooter was found.
A few minutes later, two young men got into a gun battle nearby at 2600 Stanton Road, D.C. police said. Evidence markers showed multiple bullets were fired.
Officers found one juvenile who was shot in his leg. The juvenile had a handgun, police said.
"Initially, we thought [the shootings] may be connected, but now we don't think they are," said Metropolitan Police Department Chief Cathy Lanier.
