As many as 77 bank accounts of the suspended Madhya Pradesh IAS couple, Arvind and Tinu Joshi, have been frozen and their properties attached by Income Tax authorities, who claimed that cash and investments of over Rs.360 crore were detected.

The action was taken under Section 281B of the Income Tax Act, 1961, meant to ensure that the couple cannot dispose of their properties or operate bank accounts till the completion of the probe by various investigating agencies, I-T department sources said.

A raid on the couple's residence in February last year yielded Rs. 3 crore in cash following which they were suspended. Documents relating to investments showed their worth to be a whopping Rs. 360 crore, the department said.

Jewellery worth Rs. 67 lakh, Rs. 7 lakh in foreign currency, and seven suitcases were also recovered, the department claimed. The raids were carried out following complaints that the officers had made huge investments in an insurance company.

In a 7,000-page appraisal report submitted to the State government and the Lokayukta, the department has given details of investments.
