The CBI on Friday arrested Enamul Haque, the alleged kingpin of illegal cattle trade in Murshidabad along the Bengal-Bangladesh border, from New Delhi.

The central agency in September had booked Enamul along with Satish Kumar, a BSF commandant, and a few others in connection with its probe into illegal cattle-trade in Murshidabad. Raids had been carried out across parts of Murshidabad, Malda, Calcutta, Chhattisgarh and its capital Raipur in this connection. “He will be brought to Calcutta on transit remand for questioning,” said a CBI source.

Enamul’s name cropped up when CBI officials questioned Jibu T. Mathew and Satish Kumar, both BSF commandants posted in north Bengal.

It appeared that Enamul sought their help in illegal cattle smuggling in exchange for money. “We would like to question Enamul about the role of other officers who appear to be involved in cattle smuggling,” said the source.
