Multiple people were injured when gunfire erupted in San Francisco’s Mission District neighborhood on Friday night, according to police.

San Francisco police did not reveal the number of victims or their conditions.

“Please avoid the area of 24th/Treat St as we conduct an investigation related to a shooting,” the San Francisco Police said in a statement. “Updates will be released as they become available.”

Gunshot victims were transported to San Francisco General Hospital, according to ABC7.

The shooting occurred around 9 p.m. outside a block party that was hosted by clothing retailer Dying Breed, according to journalist Matthew Keys.
