Police raid headquarters of RNC protesters

ST. PAUL, Minnesota (CNN) -- Police raided a rental hall used by a group organizing protests at the Republican National Convention in St. Paul, Minnesota, on Friday.

The RNC Welcoming Committee, which describes itself as "anarchist/anti-authoritarian," accused St. Paul police of trying to disrupt their protest planned for Monday, the day the GOP convention is set to begin.

While no one was arrested, the group said police temporarily detained and photographed at least 50 people who were inside the building.

St. Paul Police spokesman Tom Walsh said they were executing a search warrant.

"The cause for the search warrant is not public at this time," Walsh said.

As many as 30 police officers entered with guns drawn, according to witnesses in the building.

"The convergence center is simply a gathering place and is not used for illegal actions -- it is a place for workshops and trainings," a statement from the protest group said. "Tonight, we were watching films and sharing food."

"We are now accused of a simple fire code violation," the statement said.

Oddie Miller, a 19-year-old from Fort Collins, Colorado, said it was "just a space to get food, free Internet, community organization."

"There were no bombs or anything in there," Miller said.
