Stroud aerospace factory blaze investigated
The cause of a fire at an aerospace factory on an industrial estate in Gloucestershire is being investigated.
The blaze broke out at Nu-Pro's factory in Stroud shortly after 20:00 BST on Wednesday.
Nearby businesses were evacuated after fears chemicals stored at the site could catch fire.
The fire service said it had been working with specialists to clear a chemical spill caused by the fire at the Eagle Works site in Thrupp.
Nu-Pro uses the factory site to manufacture parts used in the aerospace and defence industries.
Its website says the unit is in "an industrial heritage conservation area with the River Frome running through its grounds" and it has "considerable obligations to the environment".
The 50m (165ft) by 30m (100ft) industrial building in Thrupp was "well alight" when fire crews arrived and it took more than 60 firefighters to bring it under control.
The fire service remained on site for almost 24 hours making the site safe before handing it back to the owner.
It has advised residents they "are now safe to go about their daily business".
