Sentencing of former footballer Chris Killen for a sex attack on a young woman as she slept in bed has been delayed.

The ex-Manchester City and Celtic player admitted a single charge of sexual assault shortly before he was due to go on trial at Minshull Street Crown Court, Manchester, on June 21, having earlier pleaded not guilty.

He was due to be sentenced today at the same court but the case has been re-listed for Tuesday.

Killen was in a "stupefied state" from alcohol when he went into the spare bedroom of the house the woman was staying in, in Bury, and touched her sexually.

During the hearing in June, judge Maurice Greene told the defendant: "At the end of the day this was a sexual assault on a sleeping young woman. It's a serious matter.

"All sentencing options will remain open to the court."

Lisa Judge, defending, said the guilty plea had been made on a "specific basis" as to what Killen had admitted doing, and this had been accepted by the prosecution.

The basis of the plea was not given in court and no further details about the sexual assault, which took place on September 17 last year, were made public.

New Zealand-born Killen represented his country in the 2010 World Cup after playing for Middlesbrough and Celtic and starting his career with Manchester City as a trainee.

His playing career also included stints at Hibernian, Norwich, Oldham Athletic, Port Vale and Wrexham.

Miss Judge said the defendant, of London Road, Adlington, near Macclesfield, had "no relevant" previous convictions.
