Mitie Engineering Services has been fined £300 000 after a worker was fatally electrocuted in 2005.

Michael Adamson, 26, was working at the JJB Sports Centre in August 2005 when he was killed after coming into contact with a live conductor in a cable he was working on.

The firm was found guilty of breaching the Health and Safety at Work Act and fined £300k, but two directors and the project manager were acquitted.

Despite being labelled “not in use”, the cable Adamson was working on was actually live, the Dundee sheriff court heard.

Jim Skilling, principal inspector at the Health and Safety Executive, said that Adamson had not been given the necessary equipment to prove the cable was dead.
