The agents introduced themselves as Wasiak and Krysiak. Dominik didn't bother to remember their first names, and he probably won't remember their last names either. The arrival of agents from the Central Anticorruption Bureau on his doorstep was too much of an shocking experience for him to bother with such details as the names of the agents.
The Central Anticorruption Bureau is a government agency that fights corruption among the authorities, high-ranking businessmen and public order officials. They don't bother with a corrupt traffic cop, they target his bosses, and those at the highest levels.
What, then, were they doing on the doorstep of a small actor who had no connection whatsoever with anyone who was even a low-ranking government official?
