A black Ford Ranger registration number MM55 LKA was stolen from premises on the Moss Road in Ballynure, Co Antrim.
The theft occurred in the early hours of Tuesday (January 22).
A vehicle similar to the one stolen is pictured.
Police say not only has the owner suffered the loss of his vehicle, but the business may also suffer, as it was used extensively in the day to day running of the firm.
“Someone somewhere knows where this vehicle is and who took it, and we appeal to those who do to search their conscience and assist police with arresting the offender and bringing them before the courts,” said a police spokesperson.
