Workers at a factory in Bradford were evacuated over concerns of an ammonia leak.
West Yorkshire Fire and Rescue Service were called out the Morrisons meat processing factory off Cemetery Road in Four Lane Ends on Sunday night (3 February) following reports of an ammonia alarm sounding.
Nobody reported any ill effects but staff were sent home from the site.
Morrisons said it had experienced a problem with its refrigeration system which had since been resolved and production has resumed as normal.
