The Acting Chairman of the commission, Mr Ibrahim Magu, disclosed this at an interactive session with Editors in Abuja on Wednesday.
Magu, who did not immediately give the number of the affected officials, said he would not condone any act of corruption in the agency.
“Recently, we had to discharge about nine cadet officers because they have problem with their certificates from various institutions. We are also prosecuting a lot of officers. Some of them are already in court.
“There is a way you can help us. Just like you can help us with information regarding corrupt practices outside the EFCC, and proceeds of corruption, you can also assist in giving us the information.
“But, I assure you, I do not tolerate, I won’t condone any act of corruption in the EFCC .
“I cannot be everywhere but I am telling you I don’t spare any allegation no matter how little, we make sure we investigate.
“No allegation against the EFCC personnel is left uninvestigated. Even if there is allegation against me, we will refer it to the appropriate authority to investigate.’’
The EFCC boss said that the ongoing anti-corruption war was getting tougher, saying the fight had never been this tough in the several years he had spent in the battle.
