An official said today that after more than three years of investigation against senior Indian Police Service (IPS) officer Amitabh Thakur, the Economic Offences Wing (EOW) has found him "not guilty" in a disproportionate assets (DA) case. On September 16, 2015, an FIR (No 746/2015) under Section 13(1)(e) of the Prevention of Corruption Act was registered, which was transferred to the EOW on the orders of Allahabad High Court. Following delay in investigation, Amitabh had approached the high court which directed completion of investigation in 10 weeks. In his investigation, Investigating Officer, Superintendent of Police (EOW) DPN Pandey, found that total earnings of Amitabh much lower than his earnings; between 1992 and 2015 was Rs. 1.30 crore, while the value of his total assets and expenditure was Rs. 90 lakh. Amitabh's wife and activist Nutan Thakur was also found by the EOW to be financially independent and her earnings during this period was Rs. 92 lakh, while her total assets and expenditure was valued at Rs. 90 lakh. So, the EOW recommended closure of the DA case against Amitabh. Several cases against the IPS officer by the then Samajwadi Party (SP) government had been filed , two days after he filed a complaint on July 11, 2015 against Chief Minister Akhilesh Yadav's father Mulayam Singh.
