An area of the north coast was sealed off last night following the discovery of a suspected explosive device.
A small cylinder-shaped object aroused suspicion yesterday, when it was found close to Cushendun Gaelic club.
It is not yet known whether it is an older war time bomb, or a more recent explosive device.
The area is expected to remain secured until this morning, when it is expected that army experts will inspect what has been found.
Following the end of the Second World War in 1945, huge quantities of munitions were dumped at sea in Beauforts Dyke in the Irish Sea, a sea trench between the Rhins of Galloway and Northern Ireland.
The Ministry of Defence estimates that more than a million tonnes of weapons were dumped in the long narrow trough.
Despite the passage of time, some munitions still occasionally make it to our shores.
In 2012, a young boy had a lucky escape after finding a live wartime mortar on the beach at Magilligan in Co Londonderry.
It was the third wartime bomb that had washed up on a Northern Irish shore in that year.
It was made safe by army bomb disposal experts.
