Suspected Maoists shot dead two persons, after picking the father-son duo from their home at Bandhgora area in West Midnapore district on early Sunday.
Police said the bullet-riddled bodies of Sukchand Mandi (54), a former CPI(M) activist, and his 32-year-old son Nepal were found lying on the Jhargram-Bandhgora road shortly after they were abducted from their home in nearby Mahulbani by armed men in the wee hours.
Sukchand was also a casual worker of Jhargram mini zoo which is run by the state forest department, police said. The zoo had been vandalised by Maoist-backed People's Committee against Police Atrocities (PCPA) earlier.
With several CPI(M) activists having been killed by the Maoists in Bandhgora in the past two years, the outfit is suspected to be behind today's double murder as well, police said.
