Spanish police have arrested 50 people in 15 provinces as part of an operation against the piracy of TV signals and sale of unauthorised decoders. Those arrested have been accused of crimes against intellectual property and telecommunications fraud, including managing Internet pages, distributing pirate decoders, managing local cable and TV networks and illegal distribution of TV signals. According to police estimates, the pirate network distributed more than 1,000 decoders with altered software used for unauthorised reception of pay-TV signals, achieving up to €140.000 in revenues since September 2006. A total of 14 Internet pages that distributed codes were shut down as part of the operation. The damage caused to companies, including the DTH operator Digital+, is estimated at several million euros.
