A seven-member CBI team on Saturday visited Patipukur area, the place where the body of the computer graphics designer Rizwanur Rehman was found a month ago after he died under mysterious circumstances following his marriage to the daughter of an industrialist.
The team led by Joint Director, Special Crime Cell, Arun Kumar, inspected the site for collecting evidence.
Earlier, the team held a meeting at the CBI office located inside the central government office complex at Salt Lake.
The team is likely to question Rizwanur's father-in-law, industrialist Ashok Todi on Saturday, CBI sources said.
The CBI, which has been entrusted by Calcutta High Court to probe the death of Rizwanur, who was found dead on railway tracks at Patipukur in Dum Dum on September 21, has registered a murder case against Ashok Todi.
