A man has been arrested by detectives investigating online posts relating to recent disorder in Northern Ireland.
The 32-year-old was arrested in the Larne area.
He is being held on suspicion of encouraging or assisting offences and possession of a class B controlled drug.
Officers seized a number of items including electronic devices and a small quantity of a class B controlled drug, during a search of a house in Larne.
The development follows multiple nights of rioting earlier this week in the region beginning after serious disturbances in Ballymena on Monday.
The violence, which followed an alleged sexual assault on a teenage girl in the Co Antrim town, has spread to several other parts of Northern Ireland including Larne.
More than 60 police officers have been hurt during the rioting.
