OAKLAND (AP) — Police in Oakland, Calif., have arrested two members of the Occupy movement after a downtown march.

Oakland police say a woman and a man were taken into custody late Saturday just after about 50 protesters peacefully marched from a plaza.

Police say after the march ended, about 20 protesters angrily confronted a nearby California Highway Patrol officer who stopped a driver suspected of driving under the influence. Police say officers approached the crowd to ensure the safety of the trooper, but the woman kicked one officer as police prepared to leave.

Police say she was arrested for battery on a peace officer and obstructing arrest. They say a man who tried to pull her from officers was arrested for attempting to unlawfully intervene.

No officers were injured.
