The Economic and Financial Crimes Commission (EFCC) has arrested former Governor Tanko Al-Makura of Nasarawa and his wife, Mairo, over alleged multibillion-naira fraud.
Al-Makura, now a senator, and his wife were arrested on Wednesday evening.
A source at EFCC said they were grilled late into the night at the anti-graft headquarters in Abuja.
The source did not give details of the allegation relating to their stealing public funds against the ex-governor and his wife.
Al-Makura was Nasarawa governor between 2011 and 2019 before he was elected as a senator representing Nasarawa South Senatorial District at the National Assembly.
