Oakland Mayor Barbara Lee said Saturday that she was “deeply concerned” by video and reports of San Francisco police officers smashing the glass front door of an affordable housing complex in West Oakland on Thursday. 

San Francisco police officers were in Oakland looking for an 18-year-old man, identified as Jamil Butler, who was suspected in two armed robberies in San Francisco, a spokesperson for the SFPD said in an email Sunday. 

He was found nearby the building and detained. Police allegedly found a firearm in his possession and sought search a warrant for a residence at a 79-unit affordable housing complex at Seventh and Campbell streets that SFPD said Butler was “associated” with. 

The building is owned and operated by Oakland & the World Enterprises, a nonprofit organization founded by former Black Panthers leader Elaine Brown. 

Brown said in a statement posted on her Facebook page that more than 20 officers arrived at the building without uniforms and refused to show a warrant they said they had to the building’s management. 

“They claimed to have a warrant but would not show it to building security, for which they were denied entry,” Brown wrote. 

“Instead of waiting to speak with the building’s Resident Managfbrier, Misty Cross, as requested, SFPD officers used a large sledgehammer or metal battering ram to smash through the building’s front door windows and violently enter the building.” 

Video of the incident shows the officers entering the lobby and ignoring requests by Cross to be shown the warrant. An officer asks Cross why she didn’t open the front door and proceeds to the elevator. 

The SFPD’s statement said officers were wearing police insignia and body-worn cameras. 

Butler was booked into San Francisco County Jail. 

Brown said she was filing a complaint with the Oakland Police Department against the SFPD officers alleging assault, vandalism, and violations of the Fourth Amendment. She said she “demanded criminal charges be filed immediately against the San Francisco police perpetrators.” 

The Oakland Police Department did not respond to questions Sunday about whether it had authorized or participated in the operation. 

San Francisco Mayor Daniel Lurie’s office referred questions back to the SFPD, which said officers smashed the front door because of “exigent circumstances.”
