All-clear given after bomb threat at Falls Church building where fireworks exploded in elevator

Falls Church police say the all-clear has been given after a bomb threat was called into an office building Thursday afternoon. It's the same building where fireworks exploded inside an elevator earlier in the day.

A police spokesperson said the bomb threat was called in just after 12 pm at a building located at 900 S. Washington St. Police say a witness found two sheets of paper with the word "bomb" written on both entrances of the building. Officers immediately evacuated the building when they arrived at the scene.

Bomb-detecting K-9 units from Arlington County, Virginia State Police and the Arlington County Fire Department assisted the Falls Church Police Department with the sweep of the building, but no explosive devices were found. No one was injured.

Earlier this morning, police were called to the same building after reports of smoke and a loud noise that sounded like an explosion. The building was evacuated then as well, and fire crews found exploded fireworks inside an elevator. By 9:30 am, the all clear was given, and the building was reopened.

A Falls Church police spokesperson told FOX 5 DC there are several offices in the building, including an abortion clinic, but police did not indicate that the clinic is being targeted.
