Northern Ireland Fire and Rescue Service (NIFRS) crews were tasked to the scene of a suspected gas leak at the Braidwater Retail Park at Larne Road Link in Ballymena, on Wednesday evening, 14 December.
Two Appliances were dispatched from the local Station after a report was received around 9pm.
Crews were joined by police service colleagues who closed roads to traffic around the retail unit while the scene was being investigated.
A NIFRS spokesperson commented:
"Firefighters were called to a smell of fumes. Firefighters discovered that the smell was from paint which was mistaken for gas.
