Former adviser of ex-president Goodluck Jonathan, Mr Dr Doyin Okupe was arrested by the Economic and Financial Crimes Commission.
He disclosed that he was detained today and would be arraigned on Monday next week, as against the January 18.
The anti-graft agency also confirmed the development to Channels Television in a telephone interview.
It explained that Dr Okupe was being charged for corruption and would be arraigned at the Federal High Court in Abuja next week.
Okupe, however, faulted the change of date for his arraignment by the anti-corruption agency.
According to Mr Okupe, the EFCC made the change without consultation with his lawyers.
He said his lawyers were only informed about the alteration in the date on Friday evening.
In December last year, the PDP chieftain claimed that some EFCC operatives stormed his residence in Lagos and confronted him with an allegation of cybercrime.
