Police have given an “all clear” after a bomb threat at a building that includes a women’s health clinic in Falls Church. The office building that houses the Falls Church Healthcare Center, which provides first-trimester abortions as an option for its patients, was evacuated twice on Thursday.

First, the building was evacuated after reports of smoke and explosion-like sounds in the morning around 9 a.m., according to a release from the city of Falls Church. Fire and police units from Falls Church, Fairfax County, and Arlington County all responded to the call, and found exploded fireworks in an elevator. There were no reported injuries, and the building was reopened at 9:30 a.m.

In the afternoon, the Falls Church Police Department was called back to the office building on South Washington Street after a witness found two sheets of paper, each with the word “bomb” written on them, at an entrance to the building around 12:30 p.m. The building was evacuated again.

Police brought bomb-detecting dogs to investigate the threat.

Officers reopened the building, and the right lane of traffic on S. Washington Street, after giving it the “all clear” around 2:40 p.m. No injuries were reported.

For years, protesters have demonstrated outside the Falls Church Healthcare Center, and those numbers swelled after some of the other abortion providers in Northern Virginia shuttered.

The investigation into these incidents is ongoing, and the Falls Church Police Department is asking people with information to call 703-248-5053.
