The West Bengal government has handed over to the CID the investigation into the carcass meat scam involving supply of stale meat from dead animals to eateries and departmental stores.

The development comes after Chief Minister Mamata Banerjee talked tough and formed a nine-member committee headed by Chief Secretary Moloy Dey on May 8 to look into the fiasco and fix responsibility against those aiding and abetting the crime and placing public health in jeopardy.

The investigation into the dead chicken and carcass meat allegedly procured from dumping grounds was being handled by the Budge Budge police and the SIT formed by the South 24-Parganas police, which had resulted in the arrest of 11 persons so far, including one of the masterminds, Biswanath Ghoroi alias Bishu.

The investigation also made several strides, including a breakthrough in unearthing a political nexus by bringing to book a former CPM councillor from Goyespur, Manik Mukherjee.

However, one of the kingpins in the dead chicken meat case, Kausar Ali Dhali, and his aide Rahul Vyapari are still at large.

Meanwhile, the revelation that carcass meat was being supplied to eateries in the New Market, which is right under the nose of the Kolkata Municipal Corporation and a stone’s throw away from the city police headquarters, has caused raised many eyebrows.

Police sources said Bishu, one of the key accused in the carcass meat racket, told investigators that about 40 per cent of the carcass meat procured from the dumping grounds had found its way to the New Market. The trader who deals in the said meat is now said to be on the run.

A senior officer of the SIT looking into the meat racket said the bank accounts of Bishu, containing about Rs 1 crore, had been frozen.

Apart from Bishu, his family members including his sons are also in the trade. Their bank accounts are also being probed to verify their complicity in the racket.
