Around 6:40 p.m. Thursday, a California Pacific Medical Center shuttle ran over the street median on Guerrero near 21st Street. The shuttle was apparently struck by two other vehicles and San Francisco Police officers were on the scene shortly.

According to San Francisco Police spokesperson officer Grace Gatpandan several people were injured but only one was transported to San Francisco General Hospital.

Officer Gatpandan also said a tree was knocked over when the shuttle bus veered off the road.
