The Justice Ministry's Immigration Bureau has ordered airlines not to enlist security companies to collect money from passengers awaiting deportation to cover the costs incurred during their detention, bureau officials said Monday.

The instruction follows a complaint by two Tunisians that a security company contracted by an airline extorted money from them after they were refused entry to Japan at Narita airport in June.

The bureau has issued similar orders in the past, telling airlines to collect the fees themselves. But some airlines still enlist security companies to collect the payments covering food and other costs incurred by foreigners while they await deportation, according to bureau officials.
