A 15-year-old boy who bludgeoned his mother to death with a hammer and then set her body on fire has been jailed for 16 years.
Daniel Bartlam denied murder but admitting killing his mother, Jacqueline Bartlam, after a row in the night.
The jury at Nottingham crown court heard that clips from particularly violent television shows were found on the boy's computer.
Bartlam undertook psychiatric tests and the judge, after viewing the reports, concluded he should be detained for a minimum of 16 years.
The judge lifted reporting restrictions due to the severity of Bartlam's crime.
