A Nigerian policeman has been sacked after being caught on film apparently trying to extort $150 (£100) from a motorist accused of a traffic offence.
The footage - secretly filmed on a Lagos highway - received thousands of hits on YouTube and has been replayed on Nigerian television channels.
In the film, Sgt Chris Omeleze suggests he is part of a wider corrupt network.
