LONDON — England’s Football Association has launched an investigation 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.
The FA said Wednesday in a statement that it is awaiting reports from referee Chris Foy and an FA crowd control adviser who was at the match.
The FA said that any culprit “should be subject to a lengthy ban from attending football matches.”
