500 detained in Athens crackdown
Police in the Greek capital said they have detained 501 people in an operation they say will be repeated "on a daily basis" to combat illicit trade, illegal immigration, drug dealing and other criminal activities.
The majority of those detained were foreign nationals in a sweep of central Athens.
In addition, 21 people were arrested, nine of them immigrants lacking legal documentation. Four were arrested for drug offences, five for theft, and three immigrants selling contraband goods were held for resisting arrest.
A police announcement said 455 police officers took part in the operation.
Citizens' protection minister Michalis Chrysohoidis also announced a plan to build detention centres for 30,000 illegal immigrants by 2014.
