A Trinamul worker was killed and six others were injured in a clash allegedly with BJP workers in Muktinagar village of Birbhum’s Khoirasol early on Saturday morning.

The area falls under Dubrajpur Assembly segment, which is the only seat in Birbhum district that the BJP won this time.

Police sources said the deceased was identified as Kanti Bauri, 38. Four of the six injured persons have been admitted to a private hospital in Durgapur. One of the injured is critical, police said.

Sources said that a group of Trinamul workers were attending a feast near Muktinagar village when armed BJP workers allegedly attacked them fearing that the ruling party had gathered to attack the homes of BJP workers.

“It was a planned attack by the BJP as the party won the Assembly seat. Our party workers were participating in a feast by themselves when armed BJP goons attacked them. One of our workers was hacked to death with a sharp weapon and two others are fighting for their lives,” said Malay Mukherjee, a Trinamul vice-president in Birbhum.

The BJP MLA from Dubrajpur Anup Saha, however, said the villagers had together retaliated against an attack by armed Trinamul goons.

“Armed Trinamul goons attacked the village as this area had given a lead to the BJP and helped us win the Dubrajpur Assembly seat. It was nothing but a spontaneous protest and retaliation by the villagers. There is no connection to politics at all,” said Saha.

The police said they had arrested 10 persons in this connection and started a probe into the incident.

On Saturday morning, BJP workers also allegedly attacked houses of local Trinamul leaders, including a panchayat samiti functionary of the Trinamul, in a village in Dubrajpur.

In another development, a four-member team of the ministry of home affairs reached Birbhum and visited two areas of Nanoor to talk to the victims of post-poll violence on Saturday afternoon.

Biman Bose, the Left Front chairman, said in Calcutta that had sent a letter to the ministry of home affairs and the home secretary of Bengal in protest against the continuous post-poll violence in the state. “It is important for all of us to maintain peace and tranquility in the entire state in a strict manner. We have written a letter to both the MHA and the home secretary of Bengal in this connection,” said Bose.
