Nura Mohammed was jail four months for dishonestly parading himself as a policeman.
The Judge, Abubakar Sadiq, handed down the punishment after Mohammed pleaded guilty to one charge levelled against him and begged the court for leniency.
Sadiq, however, gave Mohammed an option of N10, 000 as fine and warned him to desist from committing crime.
The prosecutor, Dalhatu Zannah, told the court that the Police Crime Prevention Unit led by Asp. David Daru attached to Life Camp Police, arrested and brought Mohammed to the Station on Feb. 1.
Zannah said on the same date, at about 11: 30 p.m. when a team of police men raided a black spot, along Daki Biyu Village, Jabi, Mohammed was found conducting himself in a questionable manner.
He said the convict had introduced himself as a police officer and showed a warrant card with his passport photograph bearing the name of Cpl. Abubakar Suleman with police number 507645.
The prosecutor told the court that in the photograph, the convict was fully in police uniform.
However, he said in the course of investigation, it was discovered that Mohammed had never enlisted into the Nigeria Police Force.
The prosecutor said the convict refused to inform the police where he got the said uniform and warrant card he use for his criminal activities.
