lnvestigations centred on German construction firm Unger this week following the collapse of a department store roof in Moscow. Several people were injured when the roof, which was used as a car park, collapsed at 11am on Sunday.
Eight cars fell through a 200m 2section onto the store floor below. A spokesman for the Moscow mayor claimed that a lack of understanding of Moscow's climatic conditions in the car park's design could be to blame. The Moscow government has imposed an immediate ban on the use of all such structures.
