Deportation has become compulsory in Dubai for those who are found guilty of flashing their middle finger in public, warned a chief prosecutor.

"'Expatriates should start having better control over their behaviour in public because, according to the Federal Penal Law, deportation has become obligatory against those who are incriminated of committing an indecent gesture or behaving obscenely in public such as flashing their middle finger, kissing, cuddling or hugging etc.

"'Emirates who commit the same crime face imprisonment, fine or both," the chief prosecutor, who requested anonymity, told Gulf News.
