The Silda attack, had left 24 paramilitary personnel dead of the Eastern Frontier Rifles. The State Director General of Police Naparajit Mukerjee on Sunday, May 22 ordered a probe into the Silda massacre after an INSAS (Indian Small Arms System) rifle looted from the Silda EFR camp was found near a CPI(M) office at Enayatpur. That's not the end of it, as an AK-56 rifle, nine other rifles, 22 pipe guns and 36 rounds of ammunition were recovered from a field, some 1.5 km away from CPI-M's Enayetpur party office.
"So far our suspicion was on the Maoists. But, now it seems CPI-M workers may have been involved," Mukherjee said. Hence, the State investigative team highlights a new angle of CPI-M's involvement in the attack though, the CID had earlier submitted chargesheets against 23 Maoist ultras, including Kishenji, the head of the insurgents.
