A fire was deliberately started in the south stand in October 1968, destroying offices, 1,400 seats and one of the team dressing rooms. The fire caused the 1968–69 Scottish League Cup Final to be postponed until April. By 1970 Hampden was starting to age as a stadium. Wembley had been revamped for the 1966 World Cup, while other major stadia were being constructed for tournaments. Public safety was emphasized after the Ibrox disaster of January 1971, when 66 spectators were crushed to death. A benefit match was played at Hampden, while the Safety of Sports Grounds Act 1975 compelled stadium authorities to obtain licences from local officials, impose crowd segregation and restrict attendances. Pittodrie and Ibrox were converted into all-seater stadiums, while Hampden's capacity was reduced to 81,000.
