Two men have been arrested by detectives investigating the bomb attack by dissident republicans on the town hall at Enniskillen, Co Fermanagh.
The men, aged 49 and 40, were being questioned about the blast, which caused minor damage to the outside of the building.
The explosion occurred on Monday night as councillors were preparing for a meeting.
The attack was later claimed by the Continuity IRA, which threatened to carry out more attacks.
Another man who was being questioned about the incident was released without charge yesterday.
