Scaffolding collapse leaves worker hanging off building and pedestrian critically injured

Three people have been injured, one critically after a scaffolding and construction elevator collapse in downtown Fort Worth, Texas USA.

According to local media scaffolding and a construction hoist outside a building undergoing renovations partially collapsed around midday on Wednesday (6 Feb).

A worker pulled himself onto the roof after dangling by his harness six stories above the ground below.

Eyewitnesses describe seeing scaffolding debris strike a woman walking by on the busy street below. The woman was hospitalised in critical condition and two other construction workers were treated and released at the scene.

Federal investigators from the Occupational Health and Safety Administration, or OSHA, are investigating.
