The 32CSM in Derry claim they have discovered a tracking device on one of its members’ cars.
A statement on their website the group says: “On bringing his car in for routine maintenance, a mechanic brought to the attention of a local member of the 32CSM that there was something protruding from the underside of the rear bumper of his car.
“On wresting the item free, the men discovered that the object was a covert tracking / listening device which had been covertly concealed, most likely by British crown forces.
“The 32 County Sovereignty Movement ask Republicans to remain vigilant and bring any suspicions or approaches to the attention of your local cumann.”
A PSNI spokesman says police do not comment on specific operational matters.
“But if anyone has any information or property it should be made available to police. No inference should be taken from this,” the spokesman says.
