Former Customs chief Abdullahi Inde Dikko is being held by the Economic and Financial Crimes Commission (EFCC).
He was yesterday quizzed over an alleged N42billion fraud.
Besides, the EFCC has traced how about N2.6billion was withdrawn from Nigeria Customs Service (NCS) coffers and remitted into the accounts of some companies floated by a former Assistant Comptroller General who served under Dikko.
Dikko was yesterday grilled on the sources of funds with which he allegedly acquired a N2 billion mansion at 1, Audu Ogbe Street, Jabi, Abuja.
The anti-graft agency had been on Dikko’s trail since January 8 when its operatives stormed his home.
