Daniel Timbers, 29, of Dereham Road, Costessey, and Barry Joy, 56, of Spencer Street, Norwich, died after an explosion at Harford Attachments on the Vulcan Road Industrial Estate on July 13.

A pre-inquest review hearing at Norfolk Coroner's Court today heard that a police investigation was ongoing and that officers were working with the Crown Prosecution Service (CPS).

At a previous hearing, senior coroner Jacqueline Lake said both men's medical cause of death was the effects of fire and inhalation of fumes of combustion pending further investigation.

Mr Timbers worked as a production operative and Mr Joy was a paint sprayer.

Detectives investigating the incident have previously told of how a build up of toxic fumes had ignited to create a 'fire ball effect'.

A further pre-inquest review hearing date has been set for April 19, 2016, before the date for a full inquest hearing is arranged.
