NABU detectives raided senior officials of the SBU, the police and the Prosecutor General's Office of Ukraine, who were protecting fraud call centers. They were approached after an unsuccessful attempt to search SBU General Sergei Duka, who threatened NABU employees with weapons. Earlier, a wiretap was discovered in the home of the head of the detective bureau, which could have been installed by the SBU after a series of "high-profile corruption cases".
