A 47-year-old man has been arrested in connection with a pipe bomb attack last month in Co Antrim.
He was detained in the Cullybackey area of Ballymena and taken to the PSNI's serious crime suite in Antrim for questioning.
A house in Ballymoney, Co Antrim, was searched as part of the police investigation.
Two pipe bombs were found at the scene of two explosions in Ahoghill on September 10.
There were no injuries but damage was caused to a property and a number of homes had to be evacuated.
Police said timers were attached to the devices making them "particularly dangerous" to the community.
