A man has been arrested on suspicion of murder after an incident in a North Yorkshire town in the early hours of Boxing Day. The victim, a man in his 20s, was pronounced dead on Tuesday morning shortly after police and paramedics arrived at Rosemary Court in Tadcaster. Police said they believed it was an isolated incident and asked the public not to speculate about what happened. A forensic tent has been erected outside a branch of Costcutter, where Rosemary Court meets Commercial Street. A cordon is in place and members of the public are being urged to avoid the area. A police spokesperson said: “The area surrounding the scene is currently closed while our officers and specialist teams carry out inquiries and the initial investigation. North Yorkshire fire and rescue service are also supporting officers at the scene with specialist screening equipment to allow a thorough investigation to take place.” They added: “At 7.20am [on Tuesday 26 December] … our force control room received a call from our colleagues at Yorkshire ambulance service who had been called to Rosemary Court in the town. A person was reporting a man with serious injuries at the location. “Officers and paramedics attended the scene and, a short time later, a man in his 20s was sadly pronounced dead. His next of kin has been informed. Although the investigation is in the early stages, we believe this is an isolated incident. “We are asking people to refrain from speculating around the death of the man and to respect the privacy of his family and friends at this extremely difficult time.”
