Office workers in the SoMa area around Wells Fargo at 2nd and Folsom are Tweeting frantically as the Bomb Squad visits the area, suiting up and entering the building. Some say they're being told to stay inside their buildings.

We'll keep this post updated, although the scare is possibly already over.

Update: Just before 3 p.m., the all clear was given for folks in the building. Phew.
