A self-erecting tower crane went over in the centre of Warsaw, fortunately no one was injured. The crane was working on the construction site of a new road flyover when it went over, as it did one of the outriggers in the base folded. The unit went over and came to rest against a viaduct. The information was sent in by a reader and we currently have no further details, a mobile crane went over in the city earlier this week.
