Samuel Orola: Tolworth school death boy tests 'inconclusive'
Police have said it is unclear why a five-year-old boy died after falling off a climbing frame in a school playground in south-west London.
Further tests are needed after a post mortem on Samuel Orola failed to establish a cause of death.
Samuel was knocked unconscious when he apparently lost his footing in the playground at Tolworth Infant and Nursery School in south-west London.
He was rushed to hospital but was pronounced dead on arrival.
The boy, who lived close to the school, had already stopped breathing when officers arrived at the scene at around 13:10 BST last Thursday following a call from London Ambulance Service.
Samuel's family paid tribute to him the day after his death, saying he was "a loving and happy boy who touched everyone's life in a very positive way".
Tolworth Infant and Nursery School has confirmed it is working with the police, local council and Health and Safety Executive, and a full investigation is taking place.
