The Abuja home of Justice Mary Odili, a Supreme Court judge, has been under siege since Friday.
Her security aides, according to report, resisted the siege by the plain-clothes officers who came to take over without an order.
But the officers have been identified as police.
No one can state categorically the reason for the siege. The police authorities and the DSS have yet to speak on the incident.
Justice Mary is the wife of Rivers ex-Gov Peter Odili who just had a court ruling ordering the Nigeria Immigration Service to return his passport seized months ago when he wanted to travel out of the country.
The service claim the EFCC put a no-fly order on the former governor.
But in a statement on Friday night, Wilson Uwujaren, EFCC spokesman, denied the agency involvement in the siege.
“The Commission by this statement wishes to inform the public that the report is false as it did not carry out any operation at the home of Justice Odili,” the statement read in part.
“If there was any such operation as claimed by the media, it was not carried out by the EFCC.”
Justice Mary Odili is the second-ranking member of the Supreme Court.
No official statement has been issued by her family or the apex court.
