Kolkata, Oct 30 (UNI) The CBI today grilled four Kolkata police officers, including two of IPS cadre, in connection with the alleged threat to computer graphics teacher Rizwanur Rahman, who died mysteriously following his marriage with Priyanka Todi, daughter of an industrialist.
''The IPS officers have said a lot of things,'' CBI Joint Director Arun Kumar told reporters.
Mr Kumar and CBI DIG Satish Golcha interrogated former Deputy Commissioners Gyanwant Singh and Ajay Kumar, who were in-charge of the headquarters and detective department respectively for about half-an-hour at a guest house.
The CBI sleuths also continued for eight hours interrogation of former Assistant Commissioner of police Sukanti Chakraborty and Krishnendu Das, who was a sub-inspector under Chakraborty in the anti-rowdy section of the detective department.
The CBI sources said the bank accounts of both Chakraborty and Das had been scrutinised.
