A suspicious object has been discovered in the Beechwood Avenue area of the city.
The object was discovered at steps leading from Marlborough Street shortly after 11am today.
The steps have been sealed off and bomb disposal experts are on their way to the scene to examine the object.
The PSNI have said the discovery of the object is linked to the arrest of a 39 year-old man in the city this morning. The man, who was arrested as part of an ongoing investigation into dissident republican activity, was taken to the Serious Crime Suite at Antrim PSNI station for questioning.
