Ik Ogbonna says this policeman robbed him of N50k(Pictured)

Here is what Ik wrote accompanying this photo

":On Saturday 8th of March 2014 I was robbed in traffic by this man who claimed to be a police man he took 50k from me .. I was able to take a pic while driving off as I had a lot doing and I Cldnt allow the foolish hungry bastard waste ma time . If u ever around ojuelegba surulere and usee this man be very careful . Ild report this to d police by tomrw but truth is... Not every police man deserves to be called an officer ".

I wonder the kind of offence which would warrant him giving 50k though...
