Police have issued advice to retailers, business owners and retail parks across Lisburn to check their premises regularly for incendiary devices.
Superintendent Philip Knox, D District Operations, urged retailers to be vigilant.
“It is good business practice to check your premises regularly for anything suspicious,” he said.
“This will help protect your staff, customers and business all year round however we would urge everyone to be particularly vigilant in the New Year when shops are busier and more people are out and about.
“Incendiary devices can be left anywhere that can catch fire easily, such as in garments, soft furnishings and upholstery. They have the potential to destroy property and take human life.
“If something looks out of place, or even just raises concern, contact police immediately.
“Never touch or attempt to move any suspicious looking objects.”
