Did the train driver also make a mistake? Prosecutor's action regarding the high-profile accident

In February, 17-year-old Dominik from Radom was severely injured while trying to help a mother with a stroller at a train station. As he attempted to reboard the train, it started moving, causing his arm to be caught in the doors and leading to him falling between the platform and the train. He lost both legs and part of his hand but has since received modern prosthetics. The train conductor, Marcin W., faces charges for failing to properly observe passenger boarding and prematurely signaling the train's departure, which endangered the lives of others. An expert opinion will be sought to assess the conductor's actions during the incident, with potential consequences including up to 8 years in prison for him.
