A woman has been arrested in connection with a police raid at a bar in the Tiger's Bay area of north Belfast.
The PSNI say 17 men who were arrested during the raid at the Alexandra Bar on Thursday evening are still being held under the Terrorism Act.
The men are being questioned about membership of a banned organisation and having items of use to terrorism.
Detective Sergeant Roy McComb said the raid was aimed at the Ulster Freedom Fighters, which is linked to the UDA.
He said were acting on information suggesting a rehearsal for a so-called 'show of strength' was in progress.
He said tactics - which included firing CS gas pellets into the bar - were used in the belief that the men were armed.
