The Police officers reportedly arrived her house in the early hours of Thursday and had now entered her premises.
The development is coming ahead of Nunieh’s appearance before a senate panel in Abuja investigating the activities of the NDDC.
Nunieh who is billed to appear before the Senate Committee probing the NDDC, however, said the policemen, whose mission she did not know, had not been able to gain access into the main building.
The security operatives were said to have arrived her residence at about 4:30 am Thursday, when she was preparing to catch the first flight to Abuja.
Nunieh is scheduled to appear before the House Committee on NDDC to give her account on the allegations of misappropriation in the Commission.
Akpabio and Nunieh had appeared before the senate ad hoc panel investigating the alleged mismanagement of N40 billion by the interim management committee (IMC) of the NDDC.
At the hearing, Akpabio said he did not know the expenditure of the NDDC under Nunieh because she refused to give him briefings.
But Nunieh said the minister engineered her removal for failing to dance to his tunes.
The ex-NDDC MD also made several allegations against the minister.
