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.

Different countries, different laws.
Don't think that just because one of these "boxes" is legal in one country that it is legal in another.
