Police investigating the death of a 16-year-old schoolboy who died after being struck by a cricket ball have confirmed his death was a "tragic accident".
Kyle Rees was taken to hospital from Portchester School in Bournemouth, Dorset, last month but died the following day despite the efforts of doctors.
A 16-year-old boy arrested on suspicion of manslaughter has been released without charge and is receiving support from authorities, Dorset Police said.
Detective Chief Inspector Kevin Connolly, the senior investigating officer, said: "Following a detailed and extensive investigation, with support from teachers and pupils at Portchester School, it has been determined that the death of 16-year-old Kyle Rees was a tragic accident involving no criminality.
"A 16-year-old boy who was arrested in connection with the incident has been released without charge and continues to receive support from the relevant authorities. Kyle's parents have been informed."
In a statement released earlier this week, Kyle's mother Tanya Cooper said she had been comforted by the tributes to her son, and would never forget the doctors who desperately battled to keep him alive.
She said: "He was cared for in a very gentle, tender and loving way by them all.
"We would also like to send our heartfelt thanks and appreciation for all of the loving wishes and beautiful words. This would have meant the world to Kyle, as it does to us, to know how many others loved him.
"Words cannot be found to explain how much he loved us or how much love we have for him."
An inquest confirmed that Kyle died following a head injury.
