With the anti-fraud bureau as they make first arrests
The UK's new National Fraud Intelligence Bureau has made its first arrests.
Part of City of London Police, the unit was set up to tackle serious organised crime, such as online scams.
The three people held are suspected of running a fraudulent ticket sales website for music and sporting events - Gigsport.com. Police believe hundreds of people may have been deceived by the online scam.
The BBC's Home Affairs correspondent Daniel Sandford was given exclusive access to the unit as it made the arrests.
