New Delhi: The Central Bureau of Investigation (CBI) has written to the West Bengal Director General of Police (DGP) to provide details of all cases of murder, attempt to murder and rape reported during post-poll violence in the state, officials said on Friday.

The agency sought the details of such cases from the DGP in line with a Calcutta High Court order that directed the CBI to take over cases related to murder, rape and atrocities against women during the violence.

The CBI has set up four teams, each headed by joint directors Ramnish, Anurag, Vineet Vinayak and Sampat Meena, to probe the political violence which ensued after the victory of the Trinamool Congress (TMC) on May 2 in a bitterly fought eight-phase assembly poll in West Bengal. Each team will have about seven members, including a deputy inspector general and about four superintendents of police, called from across the country, the officials said. The overall probe will be supervised by Additional Director Ajay Bhatnagar.

The Calcutta High Court on Thursday had ordered a CBI inquiry into alleged killings, rape and crimes against women during post-poll violence in West Bengal.

A five-judge bench, passing a unanimous judgment on a batch of PILs seeking an independent probe into incidents of alleged violence after the polls which the ruling TMC won by an overwhelming majority, also ordered constitution of a special investigation team (SIT) to probe all other cases.

The SIT will include Suman Bala Sahoo, Soumen Mitra and Ranveer Kumar, all IPS officers of the West Bengal cadre. The bench will monitor the investigations by both the CBI and the SIT, and it has asked them to submit status reports to the court within six weeks.
