DETECTIVES from Serious Crime Branch have been given additional time by a court to question a 43 year old man about the 1998 Omagh bombing and other incidents.
Seamus Daly was arrested on Monday in the Newry area.
The PSNI say detectives have been granted a further 34 hours to hold the suspect at the serious crime suite in Antrim.
Daly was one of two Real IRA suspects ordered by the High Court in Belfast to pay £1.6 million to relatives of the 29 dead after being found liable for the bomb horror.
No one was ever been convicted in a criminal court of the August 15, 1998 atrocity which was carried out by the Real IRA.
The device exploded on a busy Saturday afternoon while parents were out shopping with their children.
