The area of Cesar Chavez Street around Valencia Street and San Jose Avenue, in the vicinity of St. Luke's Hospital, has been shut down by the SFPD as they investigate a suspicious device.

No further details are available at this time, but the Department of Emergency Management says to avoid the area, and ABC 7 says there is a shelter-in-place warning. Also, the entrance to St. Luke's hospital is closed, so that may be where the device is.

We'll update you if this turns into a real situation.

Update: The situation has been cleared, according to ALERT SF. And it looks like someone made a faux bomb to scare people.

Update 2: Mission Local reports that the faux bomb, which consisted of a bottle of liquid attached to what looked like sticks of dynamite, was found on the loading dock of the Salvation Army near the hospital. The hospital and next-door construction site were both partly evacuated before the bomb squad determined that the device was harmless.
