Petronas Twin Towers in Kuala Lumpur

Thousands of people were evacuated on September 12, 2001 after a bomb threat was phoned in the day after the September 11 attacks destroyed the Twin Towers of the World Trade Center in New York City. Bomb Disposal squads found no bomb in the Petronas towers but they evacuated everyone. Workers and shoppers were allowed to return three hours later, around noon. No-one was hurt during the evacuation.[26]

On the evening of November 4, 2005, a fire broke out in the cinema complex of the Suria KLCC shopping centre below the Petronas Twin Towers, triggering panic among patrons who joined screaming in the thick, acrid smoke. There were no reports of injuries. The buildings were largely empty (except the shopping mall, Suria KLCC) because of the late hour; the only people involved were moviegoers and some diners in restaurants.[27]

On the morning of September 1, 2009, French urban climber, Alain "Spiderman" Robert, using only his bare hands and feet and with no safety devices, scaled to the top of Tower Two in just under 2 hours after two previous efforts had ended in arrest.[28] On March 20, 1997, police arrested him at the 60th floor, 28 floors away from the "summit." He made a second attempt on March 20, 2007, exactly 10 years later, and was stopped once again on the same floor (though on the other tower).[29]
