Scott Gladwin trial: Baby suffered 'catastrophic' injuries
A baby boy suffered "catastrophic" head injuries while in the care of a teenager, a court has heard.
In February 2010, Scott Gladwin, then 16, from Huthwaite, Nottinghamshire, was looking after the child while its mother went to a nearby shop.
Nottingham Crown Court heard the baby, who cannot be named, became unwell and died in hospital three days later.
The prosecution said evidence would show Mr Gladwin, who denies manslaughter, had shaken the child.
The court heard that when the four and a half month old's mother came back from the shop, she found an ambulance about to take him to hospital.
Mr Gladwin, now 20, said he had returned from the toilet to find the baby apparently having a fit.
However, a medical examination found the baby had suffered a "catastrophic" head injury, the prosecution said.
The jury was told doctors had concluded the boy had been gripped and shaken with force "far inappropriate to his age".
The trial continues.
