The building site supervisor who was on duty when a 16-year-old apprentice fell from scaffolding to his death has been found not guilty of manslaughter.

Andrew Voy, 35, had only visited the house in Camden Road, Wanstead, twice in six weeks where the company he worked for – Roof Top Rooms – were carrying out a loft conversion.

On November 14 2012 Alfie Perrin – one of two apprentices under Mr Voy’s watch – was told to clear rubbish from the roof of the site by the site foreman.

But when throwing the second bag of rubbish into the skip below he slipped and fell onto the street.

He suffered fatal head injuries on impact.

Mr Voy broke down in the dock on Monday as he told the jurors at Snaresbrook Crown Court how he had been watching Alfie from below at the time.

He later described it as “the worst day of his life” after having to give a police statement.
