An investigation into the cause of a blaze that ripped through a Watton business is continuing today.

Fire officers have this morning (Wednesday) returned to the scene on the Norwich Road Industrial Estate where re-inforced plastics company Carbonelite was gutted in the early hours of Saturday.

Fifteen firefighter crews from across Norfolk attended and spent more than five hours battling with the blaze, having to contend with high winds and flying debris.

They prevented the fire from spreading, but some neighbouring units suffered heat and smoke damage.

Serious structural damage to the building had prevented investigators accessing the building until yesterday lunchtime.
