Police investigate Man United fans' violence
England's Football Association launched an investigation Wednesday after Manchester United supporters were accused of causing substantial damage to Barnsley's stadium by ransacking catering areas during a League Cup match.
Police arrested four United fans and four Barnsley fans as the violence marred the visitors' 2-0 victory Tuesday in the fourth round.
The trouble flared at halftime in Oakwell's north stand, where about 4,000 United supporters were sitting.
