President Muhammadu Buhari on Thursday asked ministerial nominees to report to the Inspector General of Police, Mr Solomon Arase, for profiling.
Reports say some of the nominees were sighted at the Louis Edet House, headquarters of the Nigeria Police, to take part in the exercise.
They were given verification forms on police profiling to fill.
Those who have already filled the forms include Audu Ogbe (Benue), Chris Ngige (Anambra), Udoma Udo Udoma (Akwa Ibom) and Abubakar Malami (Kebbi).
Others, who are on their way include Babatunde Fashola (Lagos) and some others.
A source explained that the reason for the exercise is for the police to carry out further investigations on the ministerial nominees.
This will be a hurdle the nominees will have to scale before they appear before the Senate for full clearance.
Senate President, Dr Bukola Saraki on Tuesday unveiled the list of ministerial nominees sent by President Mohammadu Buhari.
