Charles Udoh said state authorities only learnt of the development today, and there were no prior indications from the anti-graft agency.
Udoh said more information would be provided to Nigerians about the development shortly.
A spokesperson for the EFCC did not immediately return PREMIUM TIMES phone calls and text messages seeking comments.
The development comes a day after Governor Samuel Ortom raised an alarm that the EFCC has frozen the state’s bank accounts, trapping workers and pensioners’ salaries in a state beset by hardship following months of deadly attacks by suspected herdsmen.
