Police say protesters broke windows and vandalized ATMs at several banks in downtown Oakland overnight.
Oakland police say no one was arrested and no injuries were reported after a protest march turned violent Friday night.
The Oakland Tribune reports about 50 protesters caused damage at the branches of several banks, including Bank of America, California Bank & Trust, Chase Bank, Union Bank and Wells Fargo Bank.
The newspaper reported the protesters also shattered a window pane at the landmark Tribune Tower, the former home of the Oakland Tribune.
The window was boarded up by Saturday morning.
The protest was billed as an "Anti-Capitalist Rally & March Against Police Repression" and was organized by the Bay Area Radical Action Committee.
