Students could have witnessed the last moments of a man murdered yards from their campus, say police.

Detectives have been quizzing University of Bradford students and appealing for information about the murder of Keith Cordingley, who collapsed and died after being beaten savagely about the head.

They are placing posters in student bars and advertising in the student magazine Scrapie and on the university website to trawl for useful information.

It is thought Mr Cordingley, 50, of Girlington Road, Girlington, was attacked in a flat in Easby Road on Friday afternoon. Covered in blood, he managed to stagger to the nearby Beechfield Hotel to raise the alarm.

But he died a day later from his injuries in Leeds General Infirmary, and detectives in Bradford launched a murder inquiry.

An 11-year-old boy and a 40-year-old man were arrested, interviewed and released on police bail while further enquiries are carried out. The boy has been placed in local authority care while a "small team" of officers are sifting evidence and gathering witness statements.

"We will be trying to speak to students on their home ground," said Chief Superintendent Phil Sedgwick. "People walking past at that time are likely to be students so the university is an obvious source of witnesses."

Police believe Mr Cordingley had been drinking with people at a flat in Easby Road at around 4.30pm on Friday when violence erupted.

He had injuries to his head and body which may have resulted from a beating or the use of a weapon. A post mortem examination concluded he died from multiple head injuries.

Chief Supt Sedgwick said: "We would like to hear from anyone who was in the Easby Road area from around 4pm on Friday and may have seen Mr Cordingley or anything out of the ordinary."
