Ellie Butler death: Cause of death was head injuries
A six-year-old girl who collapsed at her home in south London died from head injuries, a post-mortem examination has found.
Paramedics treated Ellie Butler at her home in Sutton on Monday but she was later pronounced dead in hospital.
A 33-year-old man arrested in connection with her death has been bailed pending further investigations.
Ellie was described as a popular child who "was always giggling away about something" by staff at her school.
Avenue Primary School head teacher Alex Clark said: "Ellie had many friends at school and this is a very sad time for us all.
"Ellie came to school every morning with a big smile on her face and was always giggling away about something.
"She was polite and well mannered and was a considerate member of the class, always kind and helpful towards her peers."
Officers from the Met Police's homicide and major crime command unit are investigating her death.
