Hossein Karrubi told Radio Farda that the authorities want to scare Karrubi, who has provided authorities with the names of four former detainees who say they were.
Hossein Karrubi said authorities also want to prevent more people from bringing their complaints of abuse to his father.
He said his father is very serious in his investigation of the reported physical abuses of the detainees and that the raid and other possible actions will not cause him to give up.
