4 of my colleagues was caught by authorities(sleeping together with no papers)..

untill now these four pairs are in jail waiting to be deported..

that person who tip these pairs was rewarded cash..

a week later my colleagues ( ladies ) flat was also search by police (whole building), but no one got caught..

keep complaining to the authorities..

who knows you will be even rewarded extra cash for it,
i've heard the reward is per head..
