Detectives are questioning former Kaduna State Military Administrator Gen. Lawal Jafaru Isa, who is also a close ally of President Muhammadu Buhari, over the $2.1billion arms deals.
Gen. Isa, who was a Military Administrator from December 1993 to August 1996, is also a respected chieftain of the All Progressives Congress(APC).
He has been undergoing interrogation in the last 18 hours at the Economic and Financial Crimes Commission (EFCC) in Abuja.
Jafaru was picked up on Wednesday night at his Ajayi Crowther Street home in Asokoro District, Abuja.
A source said: “Sometime last week, we invited Gen. Isa for interaction in connection with the ongoing investigation of the $2.1billion arms deals but he wrote us for more time.
“We waited for him to honour the invitation but he appeared to be foot-dragging.Yet, we cannot delay investigation till he has time for us.
“We effected his arrest on Wednesday night and he has been making a statement to our investigators. At the appropriate time, we will release the details.”
There were conflicting figure on exact amount for which Isa is being probed over.
A source claimed that the cash in question might be about N100million. Another said it was about N80million.
But it was gathered that Gen. Isa was grilled over some funds allegedly paid to him by the Office of the National Security Adviser (ONSA).
Gen. Isa is also a close friend of the embattled former National Security Adviser (NSA), Col. Sambo Dasuki.
