Maoist guerrillas on Friday killed a Trinamool Congress worker on the suspicion that he was working for the police at Balarampur in Purulia district.
Some armed Maoists called 52-year-old Jeetu Singh Sardar to a place near his home in Ghatbera village and strangulated him with an iron wire, Purulia Superintendent of Police Sunil Chowdhury said.
The police found Sardar's body lying by the side of a pond where some Maoist posters were found strewn. The posters claimed that Sardar has been killed for being a police informer and member of an anti-Maoist vigilante group.
Trinamool Congress activists, led by the state's Self Help Group and Self Employment minister, Shantiram Mahato, have been campaigning against Maoists in the area for sometime urging people to take part in development activity.
Mahato said Maoists would not be able to stop development in Jangalmahal comprising Purulia and two other districts of West Midnapore and Bankura by killing their activists like Sardar.
