Five people have been arrested, accused of selling set-top boxes modified to stream subscription football matches, television channels and films for free.
The sale of so-called "fully loaded Kodi boxes" has been called a "top priority" by the Federation Against Copyright Theft (Fact).
The five traders were arrested in early morning raids.
Fact said it believed the suspects had made in the region of £250,000 selling the devices online.
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.

Wait it costs more to buy online?
I think in my 45 years on this earth, and all of the times I have gone to the movies, I can count on one hand the times I was not able to get in at the time I wanted. Usually 1-2 months after release you pretty much can sit wherever you want. In no way whatsoever would I overpay to get a ticket for the theater. For a concert I can see that because, scalpers.
