英国调查伦敦剧院屋顶坍塌原因

Investigators in London are trying to figure out why part of the ceiling of a theater collapsed mid-performance Thursday, injuring at least 88 people at a nearly sold-out show.

Officials say it is not clear whether a downpour of rain just prior to the incident had contributed to the collapse. Police said there was no indication the collapse was the result of any deliberate act or attack. 

London police told VOA there were 81 so-called "walking wounded" and that seven others were taken to the hospital following the incident at the Apollo Theater.  No fatalities have been reported.

Rescue workers at the scene said all those trapped by the collapse in the century-old, 775-seat auditorium have been freed.
