 Macao: The event was held in Macau on May 3. It was the first time that the Olympic torch had traveled to Macau. A ceremony was held at Macau Fisherman's Wharf. Afterward, the torch traveled through Macau, passing by a number of landmarks including A-Ma Temple, Macau Tower, Ponte Governador Nobre de Carvalho, Ponte de Sai Van, Macau Cultural Centre, Macau Stadium and then back to the Fisherman's Wharf for the closing ceremony. Parts of the route near Ruins of St. Paul's and Taipa was shortened due to large crowds of supporters blocking narrow streets. A total of 120 torchbearers participated in this event including casino tycoon Stanley Ho. Leong Hong Man and Leong Heng Teng were the first and last torchbearer in the relay respectively.

(some of whom had already been torchbearers of other sporting events)

Which casino tycoon participated in the torch relay event?
Stanley Ho.
