A killer has been jailed for life after "viciously" murdering a man making his way home from a fundraising event in Edinburgh.

Nico Allan, 24, attacked Mark Squires in a lane off Longstone Road and left the victim with "innumerable" facial fractures.

The 44-year-old suffered a cardiac arrest and despite efforts to save him, his condition later deteriorated in hospital.

The High Court in Edinburgh heard that Mr Squires, a carer for his mother, had been attending a charity event he had arranged for a sick friend.

He and another friend were awaiting a taxi home when Allan launched an unprovoked attack on him during the early hours of October 22, 2017.

He repeatedly punched and kicked him, stamped on his head and struck him with a glass bottle.

Lord Tyre ordered that first offender Allan should serve a minimum term of 12 years' imprisonment before he becomes eligible to seek release.

He told Allan at the High Court in Edinburgh: "You committed an extremely violent attack which was both unnecessary and unprovoked."

The judge added: "It remains a mystery to me how you, a man with no record of previous offending, committed an act of such vicious and reckless violence."

Speaking following the sentencing, Nicola Patrick, procurator fiscal for homicide and major crime, said: "This was an unprovoked attack carried out with a shocking level of violence.

"It is clear Nico Allan had no thought or concern for the consequences of his actions and Mark Squires has lost his life as a result."
