Police say they have uncovered a “significant terrorist hide” containing bomb making components and explosives at Carnfunnock Country Park outside Larne.
The haul was discovered after a member of the public reported a suspicious object to police on Saturday afternoon (March 5).
According to a police spokesperson, a number of small plastic barrels had been buried in a wooded area.
Inside the barrels was a significant amount of bomb making components including partially-constructed devices and a small quantity of explosives.
Detective Chief Inspector Gillian Kearney from Serious Crime Branch said: “All of these items will be subjected to a detailed forensic examination.
“Until this has been completed, it is too early to link these items to any particular grouping, but we are following a number of lines of enquiry.
“I would ask the public to remain vigilant, wherever they are and whatever they are doing.
“If people report suspicious activity to police, we will act on it to keep people safe.
“We apologise that the park will remain closed for some time while a full clearance operation is carried out, but I hope people will understand the need to put public safety first.”
