An exchange student from Singapore managed to escape a fire at on of the dormitories on the campus of the University of California, Berkeley.
The smoke detector at the corridor alerted the police alarm system at about 4.15am on the morning of June 26.
About 200 students were evacuated, and two were admitted to hospital due to inhalation of excessive smoke.
A Singaporean student on exchange programme was fast asleep when the incident occurred.
Fortunately, he was roused from his sleep by the choking fumes and managed to escape by the stairs unscathed.
There are eight levels in the dormitory and the main affected levels were the first to the fourth levels.
The police and civil defence departments are still investigating the cause of the fire hazard.
California news reports said that a rubbish chute at Ehrman Hall that caught fire was the possible cause of the flames that engulfed the dormitory.
