A blog by a Nigerian policeman advises citizens that they can request officers are searched themselves before starting a search on a member of the public.

The website, written by DCP Frank Mba, a deputy commissioner of police, provides tips on our how to have "safe and cordial" conduct with police during an arrest.

"You may politely request that the officer be searched before searching you," one of the tips says. "Often times, this helps to allay fears that someone may be trying to 'plant' incriminating items on you or implicate you in any other way."

People have reacted angrily on social media, criticising the behaviour of the police.

It follows a series of tweets from the Nigeria Police Force last week advising people how to survive a checkpoint, after a video of an officer demanding a bribe went viral.

The blog also advises readers that they should ask to see the officer's search warrant, tell the officers about any "health challenges" and inform a friend or family member if they are arrested.
