Last night detectives from Operation Podium, the Metropolitan Police task force established to tackle Olympic-related internet crime, arrested an unnamed 39 year-old man following a raid on a business address in central Leicester.
Police said the arrest, supported by Leicestershire detectives, was part of an ongoing investigation into the "unauthorised sale of Olympic and Paralympic tickets as part of a corporate hospitality package".
Detectives have been involved in several "significant covert operations" at major events including Wimbledon, Premier League games and music concerts over the past 18 months.
Det Ch Insp Nick Downing, the officer-in-charge of the task force, said the operations were designed to ''pre-empt and disrupt" tout activities ahead of the Games.
''By taking action now we are making this a hostile environment for them to operate in,'' he said.
"The Games are a fantastic sporting event and as we have seen, there has been a huge demand for tickets. Unfortunately there will be criminals who seek to exploit this.
"At this time when the majority of tickets have been sold, the public need to be more wary than ever about buying from an unauthorised source."
Detectives have arrested 186 people with 100 facing charges, including 35 for ticket touting 29 for fraud involving ticket sales, 10 for identity cards and three for money laundering.
More than 960 people involved in previous ticket frauds or similar crimes, have been sent letters warning them to stay away from the Games.
Interpol is also helping with investigations of possible overseas ticket fraud involving a handful of websites in the United States.
