Nowak’s mother, Lucy Ross, said she thought some people had tried to use her son’s death to advance wider political arguments. “I suppose that’s the game they play, and I can’t do anything about that. But when they think it all links together – no, it doesn’t,” she said.

“Olivia’s lost her brother, and I’ve lost my son. I’m not interested in your political game. I want to know why Henry was on the floor, and he got treated the way he did, but that family got treated [in] a different way. What is that?”

Mark Nowak told ITV that his son “was not a divisive person” and the political response to his murder “didn’t sit with Henry’s values or our values”.
