This was contained in a statement issued on Tuesday by Wilson Uwujaren, EFCC spokesperson.
According to the statement, Bawa said resources spent on the congratulatory messages can be channeled to worthy causes, such as internally displaced persons (IDPs).
The anti-graft commission stated that it has observed the increasing number of congratulatory messages published in the print media by groups and individuals, adding that it is gradually turning into a distraction.
The new EFCC boss was confirmed by the Senate last week following his nomination by President Muhammadu Buhari.
The agency noted that Bawa was assuming the leadership of the commission at a time of great challenge.
The agency stated that Bawa” needs from well-wishers and indeed all Nigerians, is support and prayers, and more importantly, credible information that will further the work of the Commission.”
