Manchester United youth player Ravel Morrison fined £600

Morrison scored twice in the 4-1 Youth Cup final against Sheffield United

A Manchester United youth team star has been fined £600 by a court for throwing his girlfriend's mobile phone through a window during an argument.

Ravel Morrison, 18, of Urmston, Greater Manchester, admitted criminal damage but denied assault.

The prosecution at Salford Magistrates' Court accepted his not guilty plea on the assault count.

Morrison scored twice in the club's FA Youth Cup final victory on Monday and has represented England under 18s.

He has also played for the Man Utd first team in the League Cup.

Tina Cunnane, prosecuting, told the court Morrison and his girlfriend had been at her parents' home when the incident happened on 19 April.

She said his girlfriend had thrown the defendant's phone after reading one of his text messages and become angry.

"In retaliation the defendant threw her telephone across the room," said Ms Cunnane.

"He accepts it was retaliation, and her telephone went out of an open window."

David Fish QC, defending, told the court the couple had been together for three years and were still in a relationship.

He produced a "positive" report from probation officers in Trafford and said no violence had been used.

District Judge Jonathan Finestein told Morrison that fines were related to a defendant's income, so in his case would make for a "rather expensive" penalty for a minor matter.

Judge Finestein added: "You are somebody with a considerable future and you must at all times know that losing your temper no matter what the provocation, is not acceptable."

Morrison was fined £600 and ordered to pay £85 costs with a £15 victim impact surcharge.

The court heard that he already has one caution for common assault dating from 2008.

He is also the subject of a 12 month referral order imposed in January, and must report to probation and the Youth Offending Team in Trafford.
