Hong Kong roof collapse injures three at university

The roof of a building at Hong Kong's City University collapsed on Friday, injuring three people, officials said, sparking panic among eyewitnesses who said it sounded like an explosion had gone off.

The accident happened around 14:30 at a university sports centre in the Kowloon Tong neighbourhood, with footage showing the caved-in roof along with police, firefighters and ambulances at the scene.

The three people who were hurt have been brought to hospital, police said without detailing the extent of their injuries from the collapse, which occurred in an area used for badminton and basketball.

Such accidents are very rare in Hong Kong, a city of seven million people.
