Three fire crews were called to a false alarm at a flat in Bury St Edmunds after a ‘smoke cloak’ burglar alarm was mistaken for a genuine fire.
Two firefighters entered the property in Merchant Avenue wearing breathing apparatuses, only to discover the smoke had been created as a security measure.
'Smoke cloaks' are designed to deter intruders by filling a room with dense, harmless smoke, which obstructs vision.
The incident was reported at 8.58pm on Thursday evening after witnesses reported seeing smoke fill the property.
However, a stop was called a short while later once fire crews understood the cause of the smoke.
It is not known what triggered the system.
