The request to continue to detain Ciaran Maxwell has been approved at Westminster Magistrates’ Court.
It means the 30-year-old from Larne can now be held until Wednesday 7 September.
Maxwell was arrested in a pre-planned swoop in Somerset last Wednesday, and on Friday police were granted an extra five days' questioning time.
