Tufanganj: A 12-hour bandh call given by BJP over the suspicious death of its leader Debendra Nath Roy has turned ugly. News agencies quoted that there was a lot of vandalism.

Vehicles in Cooch Behar's Tufanganj were vandalised during a clash allegedly between Trinamool Congress and BJP supporters.

Debendra Nath Ray was found hanging near his home in Hemtabad area of North Dinajpur district on Monday morning (July 13).

Ray had contested and won the Hemtabad assembly segment -- a reserved seat for Scheduled Castes -- on a CPI(M) ticket but had switched over to the BJP last year after the Lok Sabha polls. He, however, did not resign as CPI(M) legislator in the state assembly.

The BJP leader's family has demanded a CBI inquiry into the incident as they suspected that he was murdered.

"We think he was murdered. There should be a CBI inquiry into the killing," a family member said.

The state BJP leadership termed Ray's death, as "cold-blooded murder" by the ruling Trinamool Congress party. It said TMC was wary of Ray's popularity in the area and sought a CBI inquiry into it.

BJP national general secretary Kailash Vijayvargiya said the killing of BJP leaders allegedly by TMC goons had become the order of the day in Bengal.

"It is a condemnable and cowardly act. During the rule of Mamata Banerjee, the killings of BJP leaders have become the order of the day. Hemtabad MLA Debendra Nath Ray was assassinated. His body was found hanging. Was joining BJP his only crime?" Vijayvargiya had tweeted.

Refuting the allegations, senior TMC leader and district president Kanailal Agarwal, said it was for the police to investigate the cause of Ray's death.
