Siliguri, Oct. 6: The Darjeeling district Congress today set a deadline of three days to arrest the killers of one of its block leaders. The party also demonstrated in front of Matigara police station.

Kulen Burman, 60, a leader of the Matigara block Congress, died yesterday after he was hit by Sanjoy Roy of the same locality in a salisi meeting at Patiram. Roy, a CPM supporter, was arrested.

Shankar Malakar, the Darjeeling district Congress president, said: “Burman, a leading organiser, was murdered by the criminals sheltered by the CPM. If the police missed the deadline, we will organise a larger movement.”

Jibitesh Sarkar, a CPM state committee member, has denied the charge. Burman was killed following a scuffle at the salisi meeting, he said. “There was no political connection in the incident.”

Darjeeling district police chief R. Srivastava said: “We have arrested a person. If the Congress has specific complaint against any person, they should inform us and we will take action.”
