The CBI on Tuesday questioned former Rampurhat sub-divisional police officer Shayan Ahmed and inspector in charge of local police station Tridip Pramanik for the second time in two days in connection with its investigation into the Birbhum carnage, an official said.

Ahmed was sent on compulsory waiting while Pramanik was suspended by the authorities following the incident of March 21 night in which nine people were burnt to death by unknown miscreants as a suspected fallout of the murder of a local leader of the ruling Trinamool Congress.
