SAN FRANCISCO (KRON) — Over 200 police in riot gear are responding to San Francisco City Hall where a peaceful Black Lives Matter rally turned into a massive protest causing several nearby streets to be shut down.

At around 2 p.m. Tuesday, several protesters stormed the city hall located at 1 Dr Carlton B Goodlett Place and blocked the entrance.

In Oakland, between 80 to 100 protesters have taken over the northbound lanes of Interstate 880 near the Jackson Street off-ramp. California Highway Patrol are requesting mutual aid from Contra Costa and Solano county law enforcement.

Today’s Bay Area protests — which include San Francisco, Oakland, and San Jose — and are part of a nationwide rally against the recent shooting death of an unarmed black man by a white law enforcement officer in South Carolina. The officer, who shot 50-year-old Scott, Michael Slager, initially said he fired at Scott after a tussle over his department-issued Taser. However, video recorded by a witness showed the officer shooting Scott eight times as he ran away.
