Ramzan Kadyrov is the president of the Russian republic of Chechnya, known as Vladimir Putin's attacking dog, and has been accused of serious human rights violations such as the murder and torture of dissidents and the persecution of homosexuals.
Khamzat Chimaev has been seen in both photos and clips where he hangs out and poses with the president, and has himself shared several posts with him on his social media.
SVT Sport has previously, on repeated occasions, sought Chimaev for an interview via his manager.
