A massive crowd of demonstrators have blocked Interstate Highway 880 in Oakland this evening, completely shutting it down in both directions.

According to SFist assistant editor Caleb Pershan, who is at the scene, an estimated thousand demonstrators have taken over the freeway, the culmination of a protest against the fatal police shootings of Alton Sterling in Louisiana and Philando Castile in Minnesota that began at Oakland's Frank Ogawa Plaza at 7 p.m. Thursday.

The group turned into a march by 7:25, moving north on Broadway. By 8:38, the protest had converged on 880 near the Broadway exit.

By 12:18 a.m., the Oakland Police Department reported that the size of the demonstration had dwindled to around 100 participants. As of 1:15 a.m., both northbound and southbound lanes had reopened, according to the California Highway Patrol.

According to a statement sent by OPD, vandalism was reported on Oakland's Police Administration Building. Broken windows and graffiti were also reported at some neighboring businesses, and a Caltrans signboard was set on fire on 880, police said.

An as-yet unspecified number of people were arrested during the demonstration
