Detectives from the Metropolitan police have been given an extra seven days to question a Royal Marine over the discovery of two dissident republican arsenals in Northern Ireland.
He will be held in custody for another week as searches continue in his native Larne in County Antrim in connection with the ongoing anti-terrorist operation.
Ciaran Maxwell was arrested in Somerset last Wednesday in relation to the uncovering of two terrorist arsenals near Larne in March and May.
The Police Service of Northern Ireland described the first find in May at Carnfunnock forest park as “a significant terrorist hide”. In May at nearby Capanagh forest park the PSNI along with army technical officers found homemade armour-piercing rockets and two military-grade anti-personnel mines.
The Royal Marine is being held at a London police station on suspicion of preparation of acts of terrorism. It is understood the police investigation includes the possibility of terrorist attacks by anti-peace-process republican organisations on targets in England.
