On Thursday in Austria, Magu had called on more Nigerians to take advantage of the government’s whistle blowing policy.
He said: “We are currently working on the young man because this is just a man who has not seen one million naira of his own before. So, he is under counselling on how to make good use of the money and also the security implication.
“We don’t want anything bad to happen to him after taking delivery of his entitlement. He is a national pride.”
Under the whistleblower policy, the individual who gives information is entitled to between 2.5 percent and 5 percent of the recovered loot.
But reacting to Magu’s claim on Friday, Odinkalu said the unidentified individual had been detained in three different places.
The lawyer said the whistleblower’s life could be in danger.
“The claim by @officialEFCC chair, Magu that Ikoyi Billions #Whistleblower “is now a millionaire” is verifiably false,” he wrote on Twitter.
“It’s also false that @officialEFCC has bn working with Ikoyi Whistleblower. Instead, he’s suffered serial detention in 3 difft institutions.
“I know the Ikoyi Billions Whistleblower & can confirm that he’s been despicably treated; his life cld be n danger.”
