I once met an Irish person who was detained at Beirut Airport when (trying to) leave the country, and who then disappeared into the Lebanese prison system. Really, he just disappeared.

Luckily he was allowed to make a call just after being detained, to his friend who worked for the British Council in Beirut. The friend was tirelessly in searching for him and seeking his release. It wasn’t easy.

(I met him just after his release, while he was building the courage to try again to leave the country.)

Why was he detained? Because his common Irish first name and common Irish surname matched someone on an Interpol list.
