A Larne councillor has renewed his offer to match a cash reward to identify those responsible for dumping cartons of fresh milk on the Antrim coast.
Coast Road DUP Councillor Andrew Clarke said milk cartons had "again being dumped on our lovely Coast Road".
Mr Clarke said he hated litter and added: "In fact, I would go as far as to regard it as a form of treason".
He has offered to match a £500 reward from Farmview for information on who is responsible. Farmview has confirmed that the company’s £500 reward remains available.
Director Richard McDowell said the company had not received reports of fly tipping of milk anywhere else in Northern Ireland.
Meanwhile, Mid and East Antrim Borough Council is to crack down on litter louts and dog fouling by bringing in a private enforcement company. The local authority is planning to employ a firm to patrol “hotspots” and fine offenders.
