Asst.-Cmdr. Yossi Boker, head of the Central District's Central Investigative Unit (CIU) was questioned Wednesday night by the Justice Ministry's Internal Affairs Department regarding allegations he sexually harassed his secretary. Boker was released after several hours of interrogation and was ordered not to return to his senior and sensitive post. The CIU handles most of the district's criminal investigations. This was not the first sexual harassment accusation against Boker throughout his police career. In 1993, Boker faced a disciplinary board after he stroked a secretary's hair at the Ramle police station. He was fined several hundred shekels. Recently appointed head of the CIU, Boker, from Ashdod, previously served as chief of police in Lod where he initiated the Green Island drug operation during which police arrested dozens of local drug lords and have drastically lowered the level of crime in the Lod area.
