PSNI detectives are continuing to question a 34-year-old man in connection with the Omagh bombing.
He was arrested in the south Down area yesterday morning by police investigating the Real IRA atrocity in August 1998, which killed 29 people, including a woman pregnant with twins.
36-year-old Sean Hoey of Molly Road, Jonesborough, Co Armagh, has already been charged in connection with the bombing.
His trial is expected to get under way some time next year.
