One person was killed and 15 injured Thursday when part of the stadium roof of one of the Netherland's top football clubs collapsed, the mayor of the town of Enschede, Peter den Oudsten said according to dpa. The roof over a stand at the FC Twente club stadium, in the town of Enschede, was under construction and those injured, two of them seriously, were said to be construction workers. Witnesses said there was chaos at the De Grolsch Veste stadium, where the roof of the stand collapsed within seconds at midday. Hours after Thursday's collapse, police were still using dogs and special cameras to search for people possibly trapped under the wreckage.
