DES MOINES, Iowa - More than 30 Occupy Iowa protesters have been arrested in front of the Iowa Statehouse, reports CBS Affiliate KCCI.
The demonstrators were warned twice about trespassing before the arrests began around 11 p.m. Sunday night.
Iowa State Patrol officials had warned protesters that they didn't have a permit to camp on state-owned land.
Officials with the Iowa Department of Public Safety said those arrested include 30 adults and two juveniles who were taken into custody.
Officers used pepper spray on one protester who, they say, resisted arrest.
Occupy Iowa is an offshoot of the Occupy Wall Street movement that started in New York City last month and has spread to at least 25 cities across the country.
Protesters have been speaking out against corporate greed and the gap between rich and poor people.
Similar protests are being held elsewhere in Iowa, including one in which protesters camped out at an Iowa City park.
At a Mason City event, Mark Suby of Ocupy Iowa told KCCI. "Everyone is a little ticked off about the way our economy is going, and it's a combination of a lot of things. Wall Street 's got a pipeline that goes directly to Washington, D.C. and that pipeline needs to be cut off."
