DENVER — Irish police say a woman from Leadville and three others arrested in Ireland over an alleged plot to assassinate Swedish artist Lars Vilks have been freed without charge.

Seven people — including the Colorado woman, three Algerians, a Libyan, a Palestinian and a Croatian — were arrested Tuesday in Ireland. After the arrests, U.S. authorities unsealed terror charges against Colleen LaRose of Pennsylvania. She allegedly went by the name “Jihad Jane” to recruit others online to kill the cartoonist.

Irish police said Saturday three others who were also arrested remained in custody and were being questioned.

In Leadville, a woman identified the American woman who had been held in Ireland as her daughter, 31-year-old Jamie Paulin-Ramirez. Christine Mott said she was informed of Paulin-Ramirez's arrest by the FBI and other federal law enforcement agencies.
