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.
