Police are investigating an armed raid at an industrial estate in north Belfast.
Three workers were tied up during the raid at Grange Park on the Trench Road in Mallusk at around 12.30am this morning.
A truck arrived at the scene and was loaded with copper plates worth over €30,000.
The three-man gang, armed with a handgun, escaped in the lorry and in a gold Volkswagen Passat that belonged to a member of staff.
Detectives in Newtownabbey have appealed for anyone with information to come forward.
