The FBI and police on Friday searched a San Francisco home with links to Stanislav Petrov, sources confirmed to NBC Bay Area. The 29-year-old is an auto-theft suspect who was severely beaten by Alameda County Sheriff's Office deputies, which triggered an investigation into police use of force.
Sources said the raid is tied to a federal gun investigation involving Petrov. An FBI spokesperson confirmed a home on Teddy Street in Visitacion Valley was raided around 3 p.m.
"This is a joint operation with San Francisco Police Department and the FBI," said Prentice Danner, an FBI spokesman.
Danner said the agents, armed with search and arrest warrants, were looking for "more than one person" and have made some detentions.
Friday's raid came after an overnight shooting, where sources said Petrov drove a shooting victim to a hospital. But sources said that is not why the feds responded to the home on Friday -- documents were already being prepared before the shooting.
No other information was immediately available.
