Photographer Darren Hatt caught one of the most heroic moments at a wedding over the weekend in London.
A "kid was under water on his back. He ingested water and there was mucous coming out of his nose," Hatt said.
The photographer was able to get shots of Clayton Cook, the groom, as he pulls a young boy to safety after the kid was pushed into the river by other children.
Hatt was taking photos of the bride when she started yelling! The photographer turned to see the groom jump in. "It was good timing. It happened so fast. He (Cook) must have been super quick."
