All the "Occupy Chicago" protesters arrested overnight were released on Sunday, local media in this U.S. metropolis reported.
Chicago police arrested about 175 protesters who refused to leave a downtown park around midnight Saturday.
Approximately 2,000 people marched in downtown Chicago on Saturday night and assembled in a plaza of Grant Park. Some of them insisted to stay by setting up tents and sleeping bags.
However, the police arrived early Sunday and arrested the insistent protesters, saying they were violating municipal code and would face fines. After the arrest, the police dismantled about two dozen tents and threw away some of the signs.
A protester argued that New York City has let the people stay in the park peacefully and clean up their own mess, but Chicago won't let them do the same.
One of the arrestees said that she took pride in getting arrested for standing up for her civil rights and making sure her voice was heard.
The 3-week-long "Occupy Chicago" is a local spinoff of the " Occupy Wall Street" protest that started on Wall Street in New York City and has since spread around the United States.
