Youths held over Charity Shield scuffle

The incident happened before the match

A football supporter has been taken to hospital after suffering a knife wound ahead of the Charity Shield match in Cardiff.

The fan, who has not been named, was injured in his back during a minor scuffle just before the Liverpool v Manchester United game at the Millennium Stadium.

Police have arrested two boys aged 11 and 13 in connection with the incident.

The man, thought to be from the Manchester area, is not said to be seriously injured.

There were no reports of any major disorder ahead of Sunday's match which kicked off at 1400BST.

Officers injured

On Saturday, two police officers were hurt in trouble between rival groups of fans in the Welsh capital.

South Wales Police said they dealt with several disturbances on Saturday night which were believed to have involved Cardiff City and Manchester United fans.

A total of 15 people - the majority from Cardiff and other areas of south Wales - were arrested during the evening.

One police constable was taken to hospital with a broken arm, and a dog handler was assaulted and suffered cuts and bruises.

The Charity Shield has become the first club match in British football to be played under the complete cover of a roof.

An inspection took place at 0900 BST on Sunday, when it was decided that the retractable roof should be kept shut for the Premiership curtain-raiser.
