Oakland city officials said this morning police are enforcing a notice of violation issued last week to protesters at the downtown "Occupy Oakland" encampment.
A livestream of footage from Frank Ogawa Plaza shows many police in riot gear surrounding the camp at Broadway and 14th Street. Other media footage has shown officers moving into the camp and making what appears to be arrests since 5 a.m.
Footage from the area has also shown officers disassembling tents.
Oakland City spokeswoman Karen Boyd wrote in a statement this morning that as of 4:30 a.m. the department began enforcing the "notice of violations and demand to cease violations" to people staying overnight in the plaza. A BART official said the 12th Street station is closed as of 5 a.m. with trains running through the station. The 19th Street station is open.
