False fire alert at factory creates disturbance
Neighbours may have had their sleep interrupted when a defective fire alarm continued to sound at a factory in Mertert on Saturday night.
The alarm was first triggered at the site in the "Route du Vin" at around 11.15pm.
Firefighters conducted a thorough search of the building but after 30 minutes found no fire.
When the fire alarm was reset, it was repeatedly triggered. Rescue workers concluded that a faulty detector had set off the alarm.
