Kolkata, June 12 : Enforcement Directorate (ED) sleuths probing the multi-crore school recruitment case in West Bengal has summoned the son-in-law of Sujay Krishna Bhadra a.k.a. Kalighater Kaku (uncle of Kalighat) and son of private real estate promoter Ayan Sil for questioning in the matter.

Sources said that the ED sleuths will question them about their huge assets in their names which are highly disproportionate to their income.

The central agency sleuths suspect that there is every possibility that a part of the proceeds in the school recruitment case have been invested in their properties and assets.

Sources said that under scanner of the ED officials is the source of investment in a petrol pump christened Shukla Service Centre adjacent to Durgapur Expressway where Sil's son is having a partnership. The central agency sleuths are expected to question him on funds he received to start this petrol pump.

Meanwhile, the ED sleuths have identified a common modus operandi of Bhadra, Sil and Trinamool Congress legislator and former president of West Bengal Board of Primary Education Manik Bhattacharya. "The common thing between the three is that all of them used their close family members and the bank accounts in their names to divert the scam proceeds," an ED associate said.

Bhattacharya, along with his son and wife, are currently in judicial custody for their alleged involvement in the school recruitment case.
