A Brit dad allegedly killed a Russian paedophile with a single punch after saying he wanted to have sex with his underage daughter.

The 34-year-old Brit dad is alleged to have fatally hit the Russian tourist, 36, after he made sexual advances towards his 15-year-old daughter at a pool party in Pattaya, Thailand, on May 27. The Russian reportedly told the girl he wanted to have sex with her, which led the Brit dad to punch him in the face.

In the scuffle, the Russian landed headfirst on the ground and he was rushed to a hospital in the city. He later died from his injuries.

Police in Pattaya launched a manhunt shortly afterward and collected video footage and witness statements in a bid to track the Brit down. Pattaya officers said they had identified the alleged attacker as a British national and issued an arrest warrant on the charges of “causing grievous bodily harm resulting in death.”
