A British man has been arrested in connection with the fatal shooting of a 12-year-old boy at a caravan park in the Netherlands. West Yorkshire police said a 29-year-old man, who has not been identified, was arrested at a prison in Leeds on behalf of the Dutch authorities. Danny Gubbles was shot dead in a caravan in Breda, in the south of the country, on 14 July last year in what local police described as an "extremely violent" incident. Up to seven people were seen running away afterwards and at least 10 bullet holes were discovered in the caravan. It is thought there may have been a "business conflict" over drugs. Another English national, a 24-year-old, was arrested in Amsterdam in connection with the killing. The man arrested in Leeds had been detained in prison in connection with another violent offence. He was arrested on a European arrest warrant and his extradition to the Netherlands has been requested.
