Kolkata, Oct 31: The CBI on Oct 30 began interrogating industrialist Ashok Todi in connection with the mysterious death of Rizwanur Rehman, who had married his daughter Priyanka.
Cricketer Snehasis Ganguly, elder brother of former Indian cricket team captain Sourav Ganguly, was also called for interrogation by the investigating agency at its office in Nizam Palace.
Todi's interrogation by CBI joint director Arun Kumar and DIG, S K Golcha began at 6.30 am, agency sources said adding uncle of Rizwanur's widow Priyanka Todi, Anil Sarogi, were also being interrogated.
Former city police chief Prasun Mukherjee was also likely to be interrogated later, the sources said. Priyanka and her mother had already been interrogated by the central investigating agency.
The agency on Tuesday had interrogated four top city police officers, including two former Deputy Commissioners Gyanwant Singh and Ajay Kumar.
These officers were removed earlier this month by the state government following allegations that they had pressurised Rizwanur and his wife to part.
''The IPS officers have said a lot of things,'' Kumar said last night after the interrogation. The CBI had called Sukanti Chakraborty, former assistant commissioner of the Anti-Rowdy Section of the Detective Department and Krishnendu Das, sub-inspector for interrogation at Nizam Palace.
Their bank accounts had also been scrutinised. On Oct 29, two sub-inspectors Pulok Dutta and Jayanto Mukherjee, officer-in-charge Swapan Kumar Mitra of Karaya police station and officer-in-charge of Entally police station, Pradip Dam, were interrogated.
