Report: Police warn of more parcel bombs

Scottish police investigating a series of parcel bombs sent to people associated with the historically-Roman Catholic soccer club Celtic were frantically searching Thursday for two more devices thought to be somewhere in the mail network, Sky News reported, citing sources.

Three potential witnesses were also being asked to come forward by the police investigating the "despicable and cowardly" attacks.

Police said Wednesday that two potentially lethal parcel bombs were sent to Neil Lennon — the manager of Celtic — in the attacks targeting the club, its players and supporters.

The bombs, which contained liquid explosives and nails, were intercepted before they reached the offices of the soccer coach.

Two other devices were sent to lawyer Paul McBride — who has represented both the club and Lennon — and to lawmaker Trish Godman, a member of the Scottish parliament and a high-profile supporter of the club.

Police investigating the attacks believe they are linked to the long and troubled history of sectarianism associated with Celtic, a staunchly Roman Catholic club, and its old rival Rangers, which is equally staunchly Protestant.
