Alan, the report in was in The Guardian, a reputable news source, not a tabloid rag, thank heaven. I was interested to note that the Police reported that most of the gang members arrested - including a woman who was reportedly the leader, were from Albania, as are those still being sought. One Greek was arrested - a ex- Police officer involved in providing protection.
This situation echoes news about about 6 years ago, when 70 gang members were arrested for pickpocketing focussed on the Green line (to Piraeus); 69 were Albanian, one was a transit worker.
Since 2000, Greece has been struggling with the situation of illegal Albanians ... supposedly nearly a million are in the country, the vast majority in or near the 2 major-metropolitan areas of Athens or Thessaloniki. When u consider than the total GREEK population is only a little over 11 million, you can imagine the challenges this creates. Proportionately, the US has waay less to cope with!
