A worker was seriously injured after falling from a height at a construction site in Liverpool yesterday. Merseyside police said the man, in his 30s, was taken to hospital with serious injuries to his head, back and leg. The force added that he fell from a construction site on Old Hall Street in the city center. The Liverpool Echo reported that the man fell off a lifting pole, in a position previously occupied by the same newspaper. According to its website, construction group Mac Group is undertaking a complete renovation of the building. The building is being converted into a hotel, retail and office space in a contract valued at £29m by data provider Glenigan. Merseyside police said the man is in stable condition. A spokesperson for the Department of Health and Safety said the regulator is aware of the incident and is working with Merseyside Police on the investigation. The Mac group has been contacted for comment. The accident occurred two weeks after a father and son were fatally injured when they fell from a height on a building in downtown Liverpool. David Bottomley, 53, died on the day of the accident while Clayton Bottomley, 17, died four days later. The circumstances of what happened are under investigation.
