Sukumar Murmu, the Gram Panchayat member, was arrested following a tip-off and a landmine device recovered from his house at Basantapur village, Jhargram superintendent of police Bharati Ghosh said.
This was part of a series of operations launched at various Maoist affected areas of Lalgarh and Jhargram where a bomb concealed in a tiffin box was defused earlier in the day, the SP said.
Murmu was being questioned by the police on his alleged links with the Maoists, Ghosh said.
