A 200m police cordon was setup on Friday around a garage in Buttermere Close whilst an Explosive Ordnance Disposal team search the building.
We sincerely apologise to all of those affected by today’s events. We know these are difficult circumstances but we ask for their patience and support.
This is a painstaking and methodical process in which everyone's safety is absolutely paramount. For this reason the specialist searches that are being carried out cannot be rushed.
Unfortunately this means that we are now almost certain we won’t be able to clear the cordon this evening to allow people back into their homes.”
