Several hundred empty plastic milk bottles have been found dumped on the shore outside Glenarm.
They were pictured by a local wildlife photographer on rocks and bobbing in the sea on Sunday morning.
He said that approximately 300 appeared to have been dropped onto the beach, a mile-and-a-half from ‘Madman’s Window’ on the Coast Road.
He indicated that a number have since been washed towards Glenarm by the tide during stormy conditions earlier this week.
He said that he has reported the incident to Mid and East Antrim Council.
