The San Francisco Hall of Justice was evacuated Thursday morning after a firecracker exploded inside the building, authorities said.

The evacuation in the building at 850 Bryant St. began at around 11 a.m Thursday after a woman reportedly detonated firecrackers near the store on the first floor, which started a small fire.

The suspect, 42-year-old Djuquetta Jones, was arrested. There's been no report of a motive or any injuries. 

San Francisco bomb squad is on the scene. 

All court sessions are canceled for the rest of the day, according to a tweet from San Francisco Superior Court. Potential jurors and people with court cases were told to return on Friday.

The all-clear was given at 1:38 p.m. and people were allowed back inside, according to San 
Francisco police Officer Grace Gatpandan.
