Police are going to try to switch off free streams of the Europa League final at crucial points of the match, they have warned.
Fans have been warned that illegal streams will be hunted down during the match between Arsenal and Chelsea, and they will try and shut it down in the most frustrating possible way.
The message comes as both law enforcement agencies and TV companies attempt to put people off using illegal sites and watch paid-for, legitimate services instead.
The City of London Police said illegal streams were more popular during high-profile sporting events and said people found to be sharing paid-for content can expect to be prosecuted and fined.
Detective Chief Inspector Teresa Russell, head of the Intellectual Property Crime Unit at the force said: “By illegally streaming the match, you never know when the site is likely to be shut down.“It could be at a crucial point in the match.
“In fact, enforcement agencies and companies will aim to do just that in an attempt to dissuade people from using illegal sites in the future.”
Arsenal and Chelsea will face each other in the Europa League final in Baku, Azerbaijan, on Wednesday evening.
BT Sport will be showing the match on BT Sport 2 and BT Sport 4KUHD. Fans will be able to watch a legitimate free stream, either through BT Sport’s website or on its YouTube channel.
The Champions League final will see Tottenham play Liverpool on Saturday in Madrid.
