San Francisco police were investigating a shooting that occurred sometime just after 3 p.m. on Monday on Leavenworth Street between Turk and Eddy, in the Tenderloin.

According to initial reports on the Citizen app, the shots were fired out of a gray minivan that fled westbound on Eddy Street. The SFPD only said on Twitter that there were "several victims."

KTVU reports that five people were wounded in the shooting — up from four initially reported on the Citizen app — and none of the victims' wounds appear to be life-threatening.

Parking meters along the length of Leavenworth have been taped off with police tape, and officers have reportedly located two shell casings.

The street has been closed to all pedestrian and vehicle traffic.
