Part of the Crumlin Road in Belfast was shut off for much of this afternoon amid a hoax security alert.
A number of homes were evacuated following the discovery of the suspicious object on the roof of a shop at the Ardoyne area in the north of the city.
It was reported by a member of the public at around 12.45pm, and the military moved in to investigate.
A section of the road remained closed in the area around the shopfronts, close to the Twaddell Avenue interface, from early to late afternoon.
As 5pm approached, the PSNI said the alert was over.
They said the device in question had been declared an “elaborate hoax”, and roads in the area had re-opened.
The PSNI later said: “Following further examination, police believe the elaborate hoax object left at the Ardoyne shop fronts this afternoon may have been left in the area for a considerable period of time”.
