A Dutch police chief has called for an end to “paedophile hunting” after a 73-year-old retired teacher was beaten up by teenagers and died of his injuries. Oscar Dros said there was a risk more people could die and he appealed for justice to be left to the authorities. The man from the eastern city of Arnhem was lured into having sexual contact with a minor while in a gay chatroom. Authorities said he was aware the boy was underage. But there was no evidence of past sexual contact with minors. The Arnhem attack is the latest in a series of 250 incidents involving so-called “paedophile hunters” in the Netherlands, reports say.
