Woman held after girl, 13, fatally stabbed in Doncaster park A police forensics tent covers the scene in Elmfield Park, Doncaster, where Casey-Lyanne Kearney, 13, was found with serious stab wounds. A 13-year-old girl who was found with serious stab wounds in a Doncaster park and later died in hospital, has been named by police as Casey-Lyanne Kearney. Police were continuing to question a 26-year-old woman arrested after the death of the young girl, found near a play area in Elmfield Park, on the outskirts of the South Yorkshire town. Casey-Lyanne phoned police from her mobile phone as she lay gravely injured on Tuesday afternoon. A passer-by also phoned for an ambulance. When emergency services arrived she was treated at the scene then taken to Doncaster Royal Infirmary, where was pronounced dead eight hours later, despite what police describe as the "medical staff's tireless efforts to save her." The force said the attack had been reported to them by the girl herself, who raised the alarm just before 1.20pm. The arrested woman has not been identified. At a press conference at the scene , senior investigating officer Detective Superintendent Terry Mann, of South Yorkshire Police, said Casey-Lyanne had left her home around midday on Tuesday to catch the bus to Doncaster town centre where she was planning to meet a friend. He said: "We believe that she then got off somewhere around this area here, and the next part we know is that, at 18 minutes past one yesterday, a call is received via South Yorkshire Police switchboard from Casey herself to say that she had been stabbed. At the same time, a passing member of the public has come by Casey and contacted an ambulance. In a very short period of time both police and paramedics arrived at the park area."Doncaster council confirmed the arrested woman was "known to a number of local public agencies." The park remained sealed off with a white forensic police tent a few metres from a play area. Locals spoke of their shock at hearing reports that the girl had been stabbed. One woman, who was passing with her 13-year-old daughter, said she no longer allowed her to go into the park. It is not a very good park, to be honest. A local shopkeeper, Raja, said: "They should put CCTV cameras in the park. A few customers have been saying that. He added: "It is such a shock. It is really sad. You see kids playing football in the park. It is the first time we have had a stabbing around here. But he said five or six years ago a man set himself alight in the park. Doncaster Council chief executive Jo Miller said: "We are deeply saddened by this tragic event and our thoughts are very much with family and friends ... we would urge anyone with any information to come forward and talk to the police. We can confirm that we are all working hard to piece together what happened yesterday and also gathering any information we can. The person in custody was known to a number of local public agencies and we are working together to establish all the circumstances involved with this case. She said the investigation was at an early stage and any member of the public who has any information should come forward.
