Ellie Gould was pronounced dead following the arrival of the emergency services
A 17-year-old boy has been charged with the murder of Ellie Gould, 17, Wiltshire Police said.
Ellie, who was a showjumper, was pronounced dead following the arrival of the emergency services at an address believed to be her home in Calne, Wiltshire.
The suspect, who was known to Ellie, was arrested in nearby Chippenham a few hours later on Friday afternoon.
A cordon was in operation around the house on Saturday and a post-mortem examination was being carried out to determine the cause of death.
The suspect, who cannot be named because of his age, is due before Salisbury Magistrates' Court on Tuesday.
A spokesman for Wiltshire Police said detectives were making inquiries trying to unravel the circumstances surrounding Ellie's death.
'Our thoughts remain with Ellie's family, her friends and schoolmates,' said Superintendent Conway Duncan.
