The FBI arrested several people in Minneapolis and San Diego on Sunday as part of a joint terrorism task force investigation, a spokesman for U.S. Attorney Andrew Luger confirmed Sunday evening.
A Somali woman who said she was the mother of two men who were arrested told MPR News that the FBI arrived at her house around noon. One of her sons was arrested at her house; the other was arrested in San Diego.
She said more than a dozen FBI and police officers searched her house and confiscated a tablet computer owned by the son arrested in San Diego.
She said she met with four families Sunday whose sons were also arrested in the operation.
