The family of a young father killed on New Year’s Day have voiced their anger after prosecutors ruled there would be no appeal against the killer’s sentence.

Prosecutors said the four-year sentence was not “unduly lenient”.

Former junior footballer Shaun Woodburn, 30, was found with serious injuries in the Leith area of Edinburgh at about 2am on January 1 and died later that day.

His 17-year-old killer, who cannot be named for legal reasons, was sentenced to four years’ detention at the High Court in Glasgow after being found guilty of culpable homicide. He will also be supervised for a further 18 months after his release.

The 17-year-old has lodged notice of intention to appeal against his conviction.

Mr Woodburn’s family launched a Justice for Shaun petition calling for an appeal against the sentence, which has been signed by more than 66,000 people.
