FIRE crews were called to a waterfront bar this evening after its fire alarm system went off.

Two crews from Princes Street Fire Station in Ipswich were sent to Isaac’s On The Quay at about 8.10pm after being contacted by staff, who evacuated about 200 revellers form the premises.

The fire service said the problem related to the emergency lighting but nobody was injured and customers were soon allowed back in.

Head doorman Ben Lewry, 27, praised the calm way staff had responded and customers had behaved during the incident.

Mr Lewry, whose company Titan Security runs the doors at Isaac’s, said: “All the staff did what they were trained to do and the manager said he was happy that we followed the training.

“Everybody left really nicely and because the alarm went off, they knew there might be a problem and so they cooperated.”
