A source with knowledge of the matter said that all these six properties worth crores of rupees are located in Bolpur in Birbhum district of West Bengal.

Of the six properties, five are plots of land and one is a house.

According to sources, while the properties are in the names of various associates of Chatterjee, money-trails indicate that the funds provided for the purchase of those properties came from various sources directly linked to Chatterjee.

The house in Bolpur is registered in the name of Chatterjee's former close aide Arpita Mukherjee.

The ED has so far seized cash and assets worth Rs 365.50 crore during its investigation in the school job case, which involves primary, secondary and higher secondary teachers besides teaching and non-teaching staff in Group C and Group D categories.

According to sources, ED officials are of the opinion that whatever has been seized so far is a small part of the ill-gotten gains in the school jobs case.
