British police have made four arrests so far across the London 2012 Olympics venues, a spokeswoman said Friday. The Games, centred on the Olympic Park in Stratford, east London, are surrounded by Britain’s biggest peacetime security operation. Florian Flesche, 25, from Le Revest-les-Eaux in southern France, was arrested on Sunday at the shooting at the Royal Artillery Barracks. He has been charged with common assault and is due to appear in a London court later this month. A 45-year-old man accepted a police caution for actual bodily harm after being arrested at Earls Court exhibition centre, the volleyball venue, on Sunday. A 50-year-old man who was arrested Tuesday at Lord’s cricket ground, the archery venue, accepted a police caution for theft. Petras Lescinskas, 36, from Roehampton in southwest London, appeared at Stratford Magistrates’ Court on Friday charged with a racially aggravated public order offence. Police gave no further details. A security force of more than 40,000 military and civilian personnel, backed by a huge intelligence operation, is being deployed to protect venues, athletes and millions of visitors.
