San Francisco police are responding to a shooting downtown’s Mission District and have asked people nearby to “shelter in place.”
In a series of tweets that began just after 9 a.m., police said to avoid the area of 17th Street and Vermont Avenue.
Police officials did not immediately say if anyone was wounded or killed.
The situation is ongoing and police said they would alert people when the lockdown has been lifted.
Police and city officials urged residents to avoid the area and shelter in place, said Francis Zamora, a spokesman for the City of San Francisco’s Department of Emergency Management.
He declined to release any information on the number of causalities or say it was an active shooting incident.
“We want to let the first responders go in safely first,” Zamora said.
