Police in Glasgow are investigating the murder of an Irishman outside his home in the city last weekend.

William McKeeney - a lorry driver from Malin Head in Donegal - was attacked by two men in Melville Street, Pollokshields, on Sunday.

Police said Mr McKeeney was subjected to a "sustained and violent" assault on his way home from a night out and left unconscious on the pavement.

The 57-year-old was taken by ambulance to the Victoria Infirmary where he died from his injuries.

The Department of Foreign Affairs is providing consular advice to the family of Mr McKeeney – who moved to Scotland five years ago.

His partner had heard a disturbance and saw the attack from their ground floor flat but did not realise it was him.

Officers said Mr McKeeney's partner had been left "completely traumatised" by the death.

The two men being sought by police are described as being of Asian appearance.

The officer leading the police inquiry has cautioned against speculating about the motive for the attack.

Det Ch Insp David Gailey said: "Mr McKeeney suffered massive injuries to his head and body in what can only be described as a brutal and sustained attack.

"To speculate on a motive at this time is completely unhelpful, and indeed may hinder our investigation, however, we are keeping an open mind as to why it happened."

He said Mr McKeeney and his partner were well known in the area.

''William, who worked locally as a labourer, was a popular man who was ready to help anyone he could," he added.
