Earlier this year, February 24th to be exact, Paulo Balicha a previous trainer of Shemsi Beqiri raided Reinach Superpro Sportcenter (Beqiri's gym) with around 20 masked men armed with bats and other weapons. It seemed as though Balicha and his men stormed into the gym just to challenge Beqiri to a bare knuckle fight, Shemsi being the fighter he is told his students to stay back and the two men fought for 7 minutes wearing only wraps. Balicha tries and succeeds to take Bequiri down a few a times but they always end up standing again while the masked men cheer and shout instructions like cornermen. Near the end of the video Beqiri gets the upper hand and has Balicha on his back and begins to punch and elbow his face, then we see the armed men begin to intervene and the video cuts out.
Beqiri said that Balicha attacked him with brass knuckles which is what started the brawl, it's very hard to tell if Balicha is in fact wearing brass knuckles from this video. A total of six people were injured during this escapade including Beqiri who fractured his hand and nose forcing him to pull out of his fight on Glory 14 against Murthel Groenhart. Balicha and some of his accomplices have been arrested and taken into custody.
Here is the video of most of the fight and the main piece of evidence in Beqiris case. There is some interviews and things before the fight but for those of us who don't speak german, the fight beings at 7:30.
