TheBritishHomeOffice said Friday that Reid twice stayed at Feltham Young Offenders Institution in West London -- for 10 days in 1992 and one month in 1994.
TheHomeOffice spokesman added that British police had been liaising closely with their counterparts on the Continent in an effort to minimise the impact of any hooligans who might travel abroad.
TheBritish Foreign Office told CNN that it had advised British nationals across the world to stay at home and to avoid crowded places where they could draw attention to themselves.
