The Green Acres caravan site is pictured in Leighton Buzzard, north of London, on September 12, 2011. British police raided a travellers’ site Sunday to rescue 24 men they said had been held as slaves and forced to live in squalor, some for up to 15 years. More than 200 officers from Bedfordshire Police entered the Green Acres caravan site and arrested four men and one woman, all residents on the site, on suspicion of slavery offences.
