A Kanpur resident, Shiv Kant Tripathi claimed to have received phone calls from unlisted numbers, issuing life threats to him.
"I have received several phone calls on my mobile phone with open threat of dire consequences, simply because I dared to lodge a FIR against Amar Singh for his involvement in a Rs 500 crore fraud," Tripathi told rediff.com.
In the FIR registered with the Babupurwa police station in Kanpur, Tripathi had accused Amar Singh of indulging in a fraud involving inter-transfer of funds between his different pocket companies. To buttress his charges, he had attached evidence running into almost 1,700 pages.
The Uttar Pradesh government however chose to refer the case to the Kolkata police after Amar Singh accused Chief Minister Mayawati of masterminding a 'conspiracy' and threatened to launch a counter-offensive against her.
Tripathi, who already moves around with security, said, "Anything can happen to me because I refused to withdraw my complaint against Amar Singh."
He wondered, "Why Amar Singh, who claims to be absolutely clean, was scared of facing an open investigation, after all he was not above law, and if he had done no wrong then why should he be worried?"
Responding to a pointed query about his own alleged involvement in criminal cases, Tripathi claimed, "Those are all trivial and false cases in which the police has not even proceeded against me."
He hastened to add, "And even if there are such cases against me, how does that give immunity to Amar Singh from the economic offences he has committed?"
