A pirate internet TV scam may have cost broadcasters more than £40m, according to Police Scotland.
The force is carrying out an investigation, thought to be the largest of its kind in the world, centring on the sale of illegal TV boxes to hundreds of pubs and clubs.
Officers raided two premises in Glasgow on Thursday as part of the inquiry.
The scam involves setting up TV boxes in venues to illegally stream TV, sport and films from legitimate broadcast networks.
Investigators from the Federation Against Copyright Theft (Fact) have been working with Police Scotland on the investigation for the past 16 months.
The inquiry has also been receiving assistance from the English Premier League, while officials from Sky and BT were in Glasgow to watch the raids.
A police spokesman said anyone found offering access to pirated streams of live football could face a lengthy prison sentence
