UK Police have made four arrests for London Olympics online fraud as part of an investigation into the unauthorized sale of Olympic and Paralympic tickets. UK authorities recently closed two bogus Olympic tickets web sites after an investigation that started in October last year. Police have also warned about other dangerous ticket websites such as eurosportstickets.com, jetsetsport.info, globalticketmarket.com and sportticketexchange.com. Of those, 100 people have been charged, and 57 convicted.”]
