ST. PAUL, Minn. — On the weekend before the Republican National Convention, law enforcement agencies detained dozens of people and issued a series of search warrants aimed at groups believed to be organizing demonstrations while delegates and Republican officials are in town.
Police released one person at a time from a protest-planning headquarters where people were detained in St. Paul on Friday night.
On Friday night the Ramsey County sheriff's department, accompanied by the St. Paul police, detained people inside a building here that was being used as a headquarters to plan protests.
“They handcuffed all of us,” said Sonia Silbert, 28, from Washington. “They searched everyone.”
People who had been inside said teach-ins and legal training had been conducted there, and that the space was also a repository for such items as computers and bicycles.
