The arrests came after protesters staged their march near the state Capitol even though their permit had expired.
Among the dozens caught up in the police sweep were two Associated Press reporters on assignment to cover the event. They were issued a citation and detained, along with more than a dozen other members of the media, but were expected to be let go shortly.
Marchers tried to cross two different bridges leading from the Capitol to the Xcel Energy Center, where John McCain was set to accept his party’s nomination for president. But they were stopped by lines of police in gas masks and riot gear who blocked the bridges after the marching permit expired.
A cat-and-mouse game followed as protesters moved around the Capitol area, splintered, and re-formed. The size of the crowd varied from a high of about 1,000 down to a hundred and back to around 500.
About three hours into the standoff, about 300 protesters sat down on University Avenue and police closed the four-lane boulevard. Officers then set off smoke bombs and fired seven percussion grenades, causing protesters to scatter.
Police surrounded about 200 people, including AP reporters Amy Forliti and Jon Krawczynski and reporters from other news outlets. Officers ordered them to sit on the pavement on a bridge over Interstate 94 and to keep their hands over their heads as they were led away two at a time.
The arrests came three days after AP photographer Matt Rourke, also on assignment covering the protests, was arrested. He was released without being charged Monday after being held for several hours.
A spokesman at an information center set up during the convention said 12 people had been arrested so far but that number would increase as people were processed.
Some of the scattering protesters entered a residential area north of the Capitol. Later, at least three smoke bombs were discharged in the area of apartments and houses.
About two hours into the standoff, police began arresting a handful of people even as the crowd dwindled from around 1,000 to around a hundred.
“The important thing is even though we didn’t have a permit to march, people have decided they want to keep protesting despite all these riot police,” said Meredith Aby, a member of the Anti-War Committee.
Even as protesters were being arrested, the mood was much more relaxed than earlier in the week. It even turned festive at times.
Younger people did cartwheels. Tourists came by to check out the spectacle. The chants, which were political at the outset, turned silly a couple hours in.
“You’re sexy, you’re cute, take off the riot suit,” protesters serenaded those blocking their path.
Brandon Thorson didn’t find much to joke about. The 23-year-old factory worker from Minneapolis said he just wanted to go home — but he tried to do it through police lines.
“One officer used his club to push me away and another officer hit me in the back with his club,” Thorson said. “A third officer came in and sprayed me right in the face.”
Minutes after the skirmish, Thorson’s right eye was nearly swollen shut from the pepper spray. He was not arrested.
“This is a fascist military style occupation of the city of St. Paul,” Thorson said. “Just because the Republicans are in town doesn’t mean they can turn our city into a battlefront.”
Two people — a young couple lying on the Capitol lawn — were arrested before the march began.
St. Paul Police Sgt. John Lozoya said the man was suspected of breaking a window at a Macy’s during a march downtown on Monday. He did not know why the other person, a young woman, was arrested.
Protesters circled the officers, chanting “Let them go, let them go,” as they made the arrests.
Speakers at a rally, which attracted about 500 people, angrily accused police of trying to intimidate protesters and vowed the march would go on.
“The kids were just sitting on the ground and the police walked up to them and jumped them,” said Lisa Stone, 41, of St. Paul, who witnessed the arrests. “This is a demonstration to try to promote peace. That’s not going to happen if this is the way they’re going to act. All it’s doing is hyping everyone up.”
More than 400 people have been arrested in the past week, most on Monday, when violence broke out at the end of another anti-war march.
The Anti-War Committee, which organized Thursday’s march, urged others to join in and denounced the increased presence of police in riot gear and acts of “intimidation” in the city.
Minnesota Gov. Tim Pawlenty blamed the week’s violence on a small group of “anarchists, nihilists, and goofballs who want to break stuff and hurt people.”
“They need to be dealt with,” Pawlenty said in a radio interview with WCCO-AM of Minneapolis.
Earlier Thursday, about 150 people marched peacefully from the Capitol across the Mississippi River to a park near the Xcel center, chanting: “Hey hey, ho ho, Bush and Cheney need to go to Guantanamo.”
Police said they successfully disrupted anarchists who wanted to throw Molotov cocktails, interfere with delegates and generally cause mayhem.
The American Civil Liberties Union filed a federal lawsuit on Wednesday to recover leaflets seized during police raids, claiming a violation of First Amendment rights because protesters haven’t been able to distribute the flyers.
Federal authorities Wednesday announced charges against another man accused of planning to use Molotov cocktails to attack the Xcel Center. Felony charges were also filed against eight people authorities said were core members of the RNC Welcoming Committee, a group that has worked to plan and support efforts to attack the convention.
An attorney representing the group denounced the charges.
“What they’re charged with is entering into a conspiracy to do things that essentially didn’t happen,” said attorney Larry Leventhal.
Members of the Welcoming Committee denied committing any violence.
“There are no terrorists up here. There are no terrorists in the Ramsey County Jail,” said Betsy Raasch-Gilman with the group. “There are terrorists in the Xcel Energy Center. There are terrorists in the White House.”
