The huge deposit has been traced to a bank which is believed to have assisted the money launderers to convert the cash to dollars.
There was suspicion last night that the cash may have been wired into some foreign accounts, but the government has filed an ex parte motion to place it under temporary assets forfeiture.
A telecommunications company has gone to court, claiming ownership of the money, The Nation learnt.
A whistle-blower alerted the government to strange deposits into the ECOBANK account by some suspected government officials.
Of the many deposits, about N8.4billion was singled out for investigation in the interim.
A source involved in the investigation said: “A whistle-blower alerted the Office of the Attorney-General of the Federation, leading to the involvement of the Nigerian Financial Intelligence Unit and the Economic and Financial Crimes Commission( EFCC) in the investigation.
“The probe of the account by detectives showed that the funds were routed through the account of a telecoms giant but there was no disclosure of the signatories to the account.
“Also, the list of depositors into the account was unknown but the sequence of deposits was tracked by detectives.”
The source confirmed that an ex -parte application had been filed at the Federal High Court 11 in Lagos, presided over by Justice Abdulazeez Anka, to recover the cash under temporary forfeiture.
The matter is coming up on March 3 for hearing.
The Federal Government has hired two lawyers, Mr. John Samuel Opeyemi and Mr. Oluwafemi O. Aweda, to recover the funds.
Another source also privy to the investigation said the probe so far indicated that the cash paid into the account could be over N10billlion.
The source added: “Detectives stumbled on separate deposit of N5billion and N4billion. But investigation is at present concentrated on the recovery of N8.4billion, which was changed to dollars and probably wired into some accounts abroad.
“A telecommunications giant has approached the court to claim the ownership of the cash.
“We have been demanding for the list of signatories to this account but it is yet to be provided.
The Minister of Information, Alh. Lai Mohammed, on February 12 said the whistle-blower policy had started yielding fruits, with the recovery of US$151 million and N8billion.
The Minister said: “The looted funds, which do not include the $9.2 million in cash allegedly owned by a former Group Managing Director of the NNPC (which was also a dividend of the whistle-blower policy), were recovered from just three sources through whistle-blowers who gave actionable information to the office of the Minister of Justice and Attorney-General of the Federation.
“The biggest amount of $136,676,600.51 was recovered from an account in a commercial bank, where the money was kept under an apparently fake account name, followed by
N7billion and $15million from another person and N1billion from yet another.
‘’When we told Nigerians that there was a primitive and mindless looting of the national treasury under the last administration, some people called us liars.
“Well, the whistle-blower policy is barely two months old and Nigerians have started feeling its impact, seeing how a few people squirrelled away public funds.
“It is doubtful if any economy in the world will not feel the impact of such mind-boggling looting of the treasury as was experienced in Nigeria.
‘’Yet whatever has been recovered so far, including the $9.8million by the EFCC, is just a tip of the iceberg.”
