Dhubri, Dec. 25: Dhubri police, who are investigating the death of Joydeep Chakraborty, an employee of a local business establishment, claimed to have made a major breakthrough after arresting Monisur Islam, 39, a surrendered Ulfa, suspected to be involved in the killing.
Islam was arrested on the night of December 22, in a joint operation by the army and police.
He is reported to have confessed his involvement in the killing and revealed the names of others involved in the snatching and murder.
A police source said a cattle smuggler from Gauripur town and two others from Falimari char village on the outskirts of Dhubri were involved in the crime.
Chakraborty, an employee of a firm, used to travel to the Agomoni, Halakura, Tamarhat, Golokganj and Gauripur areas of Dhubri district to collect payment from business houses.
He was killed near A.C. Barua brick kiln on December 19 when he was returning to Dhubri with Rs 4 lakh.
Sources added that the police identified the person who had fired at Joydeep and two other cart-pullers who transported goods from the business house.
Businessmen expressed great concern over the involvement of roadside vendors and cart-pullers in the killing of a trader, Jhumarmal Jain, in May this year.
Two cart-pullers were also reportedly found to be involved in Joydeep’s killing.
“We trust them (cart-puller and roadside vendors) as they transport our goods and never doubt their honesty. But if they are involved in supplying information about businessmen and their movements to the criminals, it is a matter of great concern,” a trader said.
