South Korean police raided the office of a marketing agency on Thursday as part of a fraud investigation into Cristiano Ronaldo's non-appearance in a friendly match between Juventus and a K-League selection last month.
The game has become the subject of lawsuits issued by disgruntled fans after Ronaldo remained on the bench for the entire game, despite promoters having said he was contractually obligated to play at least 45 minutes.
More than 65,000 tickets costing up to USD 330 had been sold for the July 26 game, which was organised by marketing agency The Fasta.
The Fasta issued a statement after the raid promising to "fully cooperate with the police in their investigation, so that we can clear any concerns and suspicions."
The agency also said it has "lodged a complaint with Juventus over their breach of contract."
Juventus manager Maurizio Sarri said after the match that Ronaldo stayed on the bench because of "muscle fatigue."
"It was the organiser's fault that it did not prepare for the situation. It caused the soccer fans to take all the damages. The Fasta ... should be legally liable."
