Following a peaceful Occupy Oakland anti-police brutality protest Saturday night, two people were arrested after allegedly kicking and struggling with officers, police said.

The arrests came after a group of about 20 protesters, who were among the estimated 75 that had marched through downtown and West Oakland, surrounded a California Highway Patrol officer around 11 p.m. The officer was checking a person for drunken driving when the crowd started angrily shouting, police said. But tensions eased after other officers arrived at 14th and Clay streets.

As police were leaving, a woman was arrested on suspicion of battery after allegedly kicking a police car as well as an Oakland police sergeant's leg. A man tried to pull the woman away from officers and was arrested on suspicion of interrupting an arrest. A third man struck a police sergeant in the head with a picket sign and escaped. Police did not release the names of the arrested protesters.

This is the second Saturday night march to go off relatively peacefully since a clash between Occupy protesters and Oakland police that led to more than 400 arrests in late January. After the march, protesters broke into and vandalized Oakland City Hall. Days later a judge issued stay away orders against 12 protesters.

But this week, the crowd set out by about 9 p.m. from Frank Ogawa Plaza, the one-time home of the Occupy camp, through nearby streets, and marched without any clashes. The marchers stopped briefly at deFremery Park at 18th and Adeline streets in West Oakland, where the Black Panthers gathered in the '60s and which is unofficially named after original Black Panther Bobby Hutton.

"A lot of revolutionaries have stepped on this ground," one man said to the crowd, adding that the march was held in solidarity with them.

The Occupy Oakland website says the marches will continue "weekly on Saturday -- forever."
