The proceeds generated from the criminal activities were routed through multiple persons and entities and projected as untainted assets.Investigation has further established that the Proceeds of Crime were generated from large-scale illegal recruitment of candidates in teaching posts and were subsequently concealed, possessed, acquired, used and projected as untainted property through various means.A total of three provisional attachment orders have been issued in the case amounting to Rs 301.58 crore so far.ED had earlier attached properties worth Rs 247.35 crore in the case of Group C & D staff SSC Recruitment Scam in West Bengal. In SSC Assistant Teacher Recruitment Scam (9th to 12th), the ED has attached properties worth Rs 301.58 crore.In yet another case of Primary Teachers Recruitment Scam in West Bengal, the agency has already attached/seized properties worth Rs 154 crore.
