to one hour before the explosion. As the vehicle had stopped in Oldham, Manchester Chorlton Street coach station, and finally Huddersfield to collect returning service personnel and their families prior to travelling towards Catterick Garrison, a possibility existed the device could have been placed in the vehicle in any of these three locations, although the timing of the explosion indicated the device would unlikely have been placed upon the vehicle in Huddersfield. Investigators initially remained open-minded as to whether the perpetrator was a member of a UK-based cell, or had travelled across from Northern Ireland to commit the atrocity, as had been the case with regards to a previous IRA bombing at the Old Bailey.
