The Economic and Financial Crimes Commission (EFCC) is investigating the Head of Service, Winifred Oyo-Ita.

According to ChannelsTV, the head of the federal civil service is being quizzed by the anti-graft agency for alleged N3 billion contract scam.

ChannelsTV reported sources as saying that she was also being investigated for alleged abuse of duty tour allowance, money laundering and alleged theft of government funds.

Oyo-Ita is said to have been granted an administrative bail but is now hospitalized under the close watch of the anti-graft agency.

She was appointed as the head of the civil service of the federation in an acting capacity in October 2015 and confirmed in January 2016 by President Muhammadu Buhari.

It is also believed that the EFCC has widened its dragnet in search of cronies and aides of the Head of the Civil Service of the Federation, Mrs Winifred Oyo-Ita, involved in alleged N3bn bribery, duty tour allowance falsification and fraud case.

Our correspondent gathered in Abuja on Thursday that EFCC detectives were still following the trail of how Oyo-Ita used proxies to obtain money from contractors handling various projects in Ministries, Departments and Agencies in the country.

Some contractors who allegedly gave her bribes have been identified and would also be invited for questioning, it was learnt.

The bank accounts of a number of the suspects were said to have been frozen, including that of the HoS’.

Preliminary findings had confirmed that about N3bn lodged in her accounts were from proxy companies and contractors.
