The Central Bureau of Investigation (CBI) Thursday interrogated Priyanka Todi for the second time in connection with the mysterious death of her husband Rizwanur Rahman in September.
A three-member women's team went to her Salt Lake residence around 9 am and questioned her for three hours, a day after her father, industrialist Ashok Todi, was interrogated by CBI sleuths for 10 hours.
The CBI had earlier questioned Priyanka at her uncle Pradip Todi's house on Oct 23, almost a month after her husband, 30-year-old graphics designer Rizwanur Rahman, was found dead on railway tracks Sep 21.
Officer-in-charge of Kolkata Police's anti-rowdy section Sadhan Sinha, who had allegedly threatened Rizwanur, was summoned to the CBI's Nizam Palace office and questioned about his alleged involvement in the case. Association for Protection of Democratic Rights (APDR) member Sudipto Sen was also quizzed.
Both Sinha and Sen were interrogated by CBI Deputy Inspector General (DIG) Satish Golcha for about two hours.
Rizwanur had been in touch with the APDR before his death and had given a written complaint of harassment by top cops.
Cricketer Sourav Ganguly's brother Snehasish, who is a director in Todi's company Lux Cozi, was also called in for questioning Wednesday. Todi's brother Pradip and nephew Anil Saraogi were questioned, too. So was Trinamool Congress legislator Javed Khan, a senior CBI official told reporters.
Ganguly had earlier admitted to introducing the industrialist to former police commissioner and Cricket Association of Bengal (CAB) president Prasun Mukherjee - removed from his post following the controversy over the death of Rizwanur, who was found dead with his head smashed barely a month after his marriage to Priyanka.
Mukherjee is also likely to face CBI interrogation, sources said.
