One was arrested during a largely peaceful anti-police march through downtown Oakland Saturday night, police said.

Oakland police said around 60 people gathered in Frank Ogawa Plaza at 8 p.m. for a march that circled through downtown Oakland between 9 and 11:30 p.m.

One protester was arrested when the demonstrator blocked the roadway with garbage, police said.

An announcement of the march posted to Facebook had suggested protesters might target police and media property, and set fires in the streets.

The march was the third weekly anti-police march organized by some Occupy Oakland demonstrators in response to what they call ongoing harassment by Oakland police.

Organizers have said that the anti-police marches would be a weekly event on Saturday nights.

Last week, two were arrested during a largely peaceful march. On Jan. 7, six were arrested in clashes with police for a variety of charges including vandalism, assaulting police officers and possession of explosives.
