Five people have been arrested in early morning raids for selling "fully loaded Kodi boxes," which are set-top boxes modified to stream subscription football matches, television channels and films for free. The Federation Against Copyright Theft (FACT) said it believed the suspects had made roughly $250,000 selling the devices online. BBC reports: Kodi is free software built by volunteers to bring videos, music, games and photographs together in one easy-to-use application. Some shops sell legal set-top boxes and TV sticks, often called Kodi boxes, preloaded with the software. The developers behind Kodi say their software does not contain any content of its own and is designed to play legally owned media or content "freely available" on the internet. However, the software can be modified with third-party add-ons that provide access to pirated copies of films and TV series, or free access to subscription television channels. The five arrests were made in Bolton, Bootle, Cheadle, Manchester and Rhyl.
