A man jailed for the murder of his partner's 13-month-old son has lost an appeal against his conviction.
Noah Serra-Morrison was found dead at his home in Crawley Road, Luton, in November 2015.
He had head injuries caused by blows with a blunt intrument and multiple fractures to his arms and legs.
Medical experts said his injuries were so severe they were similar to those suffered by people in car crashes or high falls.
Hardeep Singh Hunjan, 28, was convicted of murder in July 2016 and jailed for at least 23 years.
He took his case to the Court of Appeal but it was thrown out by judges yesterday.
Mr Justice Jay said there was nothing to suggest his conviction was tainted.
