Founder of Daar Communications, Raymond Dokpesi, has been interrogated by the Nigeria Immigration Service (NIS) in Abuja.
Sources say Dokpesi was told to come with his international passport to NIS headquarters in Abuja on Wednesday.
He was later released after over three hours spent at the Comptroller General’s Investigation Department.
Dokpesi was last Friday arrested by Immigration officers at the Nnamdi Azikiwe International Airport, Abuja.
He had just returned to Nigeria after receiving medical treatment at the American Hospital, Dubai.
The media mogul was later released after over an hour in detention.
