CHICAGO (CBS) — A small group of Occupy Chicago activists marched through downtown Chicago Sunday night, in a hastily-called march to protest the arrest of their fellow demonstrators at gatherings in St. Louis and New York City over the weekend.

As WBBM Newsradio’s Dave Marsett reports, the Chicago Tribune says the group marched from the Federal Reserve to Millennium Park, and changed against police brutality. Bicycle-mounted police officers rode alongside the group as they marched down Washington Street.

In New York over on Saturday, dozens of protesters were forced out of Zuccotti Park by police and arrested, the Tribune reported. The Occupy Wall Street group had hibernated through most of the winter, but had planned a rally in Zuccotti Park to mark the six-month anniversary of the movement.

Fifteen people were also arrested in St. Louis during the Occupy the Midwest regional conference, the Tribune reported.

In Chicago, contact between police and protesters was limited to a clash involving one demonstrator waving a sign reading, “F**K THE POLICE,” the Tribune reported. A bicycle officer took the sign away from the demonstrator, who was standing near the Bean sculpture in Millennium Park.

The demonstrator told the Tribune the officer said, “I don’t like (the sign)” and took it. The protester complained to the newspaper that his First Amendment rights were being violated.
