Last week police warned members of the public in the Whitehouse Road area to be vigilant and to report any suspicious objects to police.
At the time, a police spokesperson revealed a thorough search had carried out following information that suggested there may be something suspicious in the area.
The spokesperson said officers went door to door talking to local residents and while nothing was found police asked should someone come across a suspicious object they do not touch it and contact police immediately.
