Debtor's prison in Dubai

From an article about debtor's prison in Dubai.

He'll stay there longer if no one steps forward to pay his $44,700 debt.

"If they cannot pay, we cannot release them," said Lt. Col. Abdulhalim Mohammed al Hashimi of the Dubai Central Prison.

Apparently, 40% of the prison population are there because they can't pay there debts. Now, I may be missing something here, but the words 'catch' and ' twenty-two' are ringing pretty loudly.
