Suspended IPS officer Amitabh Thakur on Tuesday demanded Rs 10,000 from the Uttar Pradesh Vigilance Establishment as expenses for providing the documents sought from him in the disproportionate assets case.

In a letter to investigating officer Daddan Chaubey, Thakur said, "I have been asked for Income Tax returns for the period 1992-93 to 2015-16, details of the house and car loan taken from Allahabad Bank, Gonda, certain amounts deposited in Ballia in 2002 and Meerut in 2011 etc.

"As most of these documents are not available with me and I will have to go to Gonda, Ballia, Meerut and Bokaro (Jharkhand), where my IT returns are filed, it will require money."

He said although he is willing to provide all the required documents but it is also the duty of the Vigilance Establishment to provide him the expenses incurred in procuring these documents.

"I need Rs 10,000 from the department to provide the necessary information," he said.

The disproportionate assets case was registered against him at Gomtinagar police station in Lucknow. Thakur was suspended by the state government after he had filed an FIR against Samajwadi Party supremo Mulayam Singh Yadav for allegedly threatening him.
