Roof of Hong Kong university gym collapses; 3 hurt

The roof of a Hong Kong university gym collapsed Friday, leaving three people hurt and triggering temporary panic among students who thought it was an explosion.

The City University of Hong Kong said the roof of one of the halls at its sports center fell at around 2:30 p.m., and two members of staff were hurt and a third was in shock.

It said in a statement that there were no reports of any people being trapped inside.

Local TV news showed firefighters arriving and being lowered to the accident site.

Local broadcaster RTHK quoted a student surnamed Tsui as saying people ran away from the area shouting, "Something is exploding."

The cause of the collapse is being investigated.
