On 29 October 2007, while travelling to a show in Gomel, Belarus, the bus carrying Decapitated and Crionics was involved in an accident.

The tour bus collided with a truck carrying wood, causing serious head injuries to both Kiełtyka and Adrian Kowanek.

While Kiełtyka's family released a statement saying that his condition had improved, he underwent trepanation and was due to be transported to a hospital in Kraków, Poland, for further treatment.
