THE Orange Volunteers have claimed responsibility for the security alert at the Sinn Fein's office in Cookstown on Monday.
Police received a tip-off that a suspicious device had been located outside the building on the Burn Road and the area was subsequently closed off after 3pm.
A search was initiated and as the police were evacuating residents, a suspicious object was discovered a few feet away from the Sinn Fein office.
An army technical officer was tasked and x-rayed and dismantled the short length of pipe which was sealed at either end with a granular substance.
As the operation was underway, Downtown Radio were informed by a male caller that the Orange Volunteers were claiming responsibility for the pipe bomb device.
Police enquiries are on-going and anyone who noticed anything suspicious has been asked to come forward.
