German Bundesliga football club Bayer Leverkusen has called on its fans to help tackle the unofficial secondary ticketing market.
The club has placed ticket collection boxes at three locations around its BayArena home ground. Leverkusen is encouraging its supporters to throw their tickets into the anonymous boxes after each game.
The club said from the tickets collected, it will then check the resellers and take legal action against them.
The statement said: “The aim of this approach is to combat and limit the uncontrolled trade in tickets – in particular to protect their own fans and all stadium visitors.
“A separation of rival fan groups as well as the exclusion of violent stadium visitors is not possible with the resale of tickets over the unofficial ticket market.”
Leverkusen also warns its followers against the purchase of tickets via unofficial secondary market platforms, including eBay, Viagogo and StubHub.
