Mariusz Węgłowski has been in love with his wife, Agnieszka, for 25 years. Their happy life was cut short by the death of their daughter.

A tough guy
with a heart of gold. What's Mariusz Węgłowski like in person?
During an interview on "Halo, tu Polsat," he was asked if he draws on his police experience in the series. He said, "I'm drawing on it to the fullest, because all the situations you see on screen—shootouts, chases, tactical interventions—bring me a certain ease." These action scenes are much closer to Mariusz Węgłowski than love stories. "A wolf is drawn to the forest, so I prefer crime stories and mysteries. The writers' limitless imagination keeps it constantly exciting. My past means I have to be a constant 'man in action.' There's always something going on there," he confessed in the aforementioned interview.
