Contradictions from key Omagh bomb witness scupper prosecution

Fatal contradictions in the evidence of the prosecution's key witness prompted the collapse of the Omagh bomb case.

Denis O'Connor, a builder from Kilkenny, had claimed he received a call from Seamus Daly around 20 minutes after the bomb detonated on August 15, 1998.

The claim was crucial to the case, as the call made to Mr O'Connor was from a phone prosecutors believed was used by one of the Omagh bombers.
