CID Special Superintendent Bharati Ghosh said Pandey, CPI(M)'s Binpur zonal committee secretary, was arrested from Chandrapura in Bokaro district of Jharkhand yesterday.
CID had produced Pandey before a Bokaro court and obtained a transit remand for him. He would be produced before a court in Burdwan district in West Bengal later in the day, she said.
With Anuj Pandey's arrest, altogether six persons were taken into custody since April 30 when five more accused in the case were captured from a hideout in Hyderabad.
Of the 20 accused in the case, 18 have so far been arrested while two, Fullara Mandal and Chandi Karan, are still absconding.
Nine persons were killed in indiscriminate firing allegedly from Dandapat's house at Netai village in West Midnapore district on January 7, 2011.
The Calcutta High Court had ordered a CBI inquiry into the massacre in February, 2011 expressing dissatisfaction with a CID probe then.
