Nigeria drig outfit, the National Drug Law Enforcement Agency, has grilled billionaire night club operator, Obinna Iyiegbu aka Obi Cubana.
He was interrogated over alleged dealings with narcotics kingpins.
He is suspected of having received payments into his bank accounts.
The payments came from suspected drug lords in Malaysia, India and Nigeria.
He was grilled at the agency’s office in Abuja for five hours on Thursday.

He attracted public attention with the obscene display of cash at his mother’s burual in Oba, Anambra State last year.
