Former National Security Adviser, Colonel Sambo Dasuki (retd), was Tuesday morning arrested at his Asokoro, Abuja residence by operatives of Department of State Service (DSS).
He was taken to the DSS headquarters at Aso Drive, Asokoro, Abuja where he is expected to answer questions on the multi-billion naira arms contract he awarded while in office.
Dasuki had been placed under house arrest in his Abuja home since November 4, 2015 by the DSS.
That was a day after Justice Adeniyi Ademola of the Federal High Court sitting in Abuja granted him leave to travel abroad for medical treatment.
The court gave him three weeks for the trip.
He was expected to return November 26, 2015.
However, the DSS said Dasuki had been indicted in another investigation involving the purchase of arms during the regime of former President Goodluck Jonathan when he served as NSA.
He denies all allegations of corruption and gun-running levied against him.
