Three men were arrested on terrorism charges Saturday. They are accused of building Molotov cocktails and planning attacks at President Obama's Chicago campaign headquarters and at the home of Chicago Mayor Rahm Emanuel during the NATO Summit, prosecutors said.
Brian Church, 20, of Ft. Lauderdale, Fla., 24-year-old Vincent Betterly of Oakland Park, Fla., and 24-year-old Jared Chase of Keene, N.H., are charged with conspiracy to commit terrorism, providing support for terrorism and possession of an explosive or incendiary device.
"These men were here to hurt people," Cook County State's Attorney Anita Alvarez said in a news conference.
The defendants are self-proclaimed members of the Black Bloc group.
In addition to materials to make molotov cocktails, police say the defendants had various weapons, including a mortar gun, swords, a hunting bow, throwing stars, knives, brass knucles.
"This plot does not represent protest behavior, this is criminal behavior," said Chicago Police Superintendent Garry Mccarthy.
The men argue the materials police collected in an overnight raid Wednesday were used to brew beer.
In a differant case, two militia men from Wisconsin were arrested after police found shotguns, shells, extended clips, knives and batons inside their vehicle during a traffic stop. Both men were wearing militia uniforms and were riding in a car that flew a militia flag, police said.
Police said they believe the men were in town to protest NATO.
A Chicago man was also charged with conspiring to build a Molotov cocktail and will appear in court today, the Sun-Times reported.
