The Economic and Financial Crimes Commission (EFCC) has reportedly obtained a warrant from a court to search all the apartments in Osborne Towers, where about $50m was discovered last week.
Sources said EFCC has written to all the occupants of the building notifying them of plans to search of all the apartments.
It was learnt that the reason for the search arose from the suspicion that there might be more cash hidden in another apartment at Osborne Towers, other than Flat 7B.
A source revealed that the whistle blower who blew the lid on Apartment 7B, had also informed the commission that another apartment has cash stashed in it.
The whistle blower, the source said, is believed to be a young graduate who works in the building.
It was for this reason that the commission went to court to obtain a warrant to search all the apartments in the building.
TODAY reports that upon receiving the letter of the EFCC, several occupants of the building were very co-operative at the weekend and allowed the operatives to carry out a search of their flats.
According to the source, about 21 flats in the building had already been searched by Monday, including the penthouse and three flats belonging to the former National Chairman of the Peoples Democratic Party (PDP), Alhaji Adamu Mu’azu.
