A suspicious package forced the closure of Parnassus (between Third and Fourth Avenues) near UCSF. "The San Francisco Police Department's bomb squad has been called in, and a nearby UCSF childcare facility has been evacuated," reports SF Appeal.

Also, according to SF MTA, the 6 and 43 lines have been rerouted around Parnassus. We'll update as soon as the Monday morning melee clears.
