By virtue of the provisions of the law,
only a court can compel the appearance of a suspect. 
Section 113 of the
Administration of Criminal Justice Act 2015 states that –

“ A court may issue a
summons or warrant as provided in the Act to compel the appearance before it of
a suspect accused of having committed an offence in any place, whether within or
outside Nigeria, triable in a state or in the FCT”.

The Act does not in anyway
empower the police to declare a person wanted without a warrant for that
persons arrest issued a court of competent jurisdiction.
