Fifteen people are to appear in court in Manchester today, following disturbances on a train bringing football supporters back from matches in London. Eye witnesses report that the trouble began when groups of rival supporters whose teams had both been playing London clubs began to insult each other. After fighting had broken out police boarded the train just outside Manchester and arrests were made. British Rail have announced that they are considering withdrawing all soccer specials operating from Manchester.
