IRA infiltrator denies 'mole lies'

A former British double agent in the IRA has denied being a pathological liar over claims a suspected Garda mole destroyed evidence from one of the worst atrocities in the Troubles.

Peter Keeley told a tribunal into alleged Garda-IRA collusion that he heard a detective got rid of vital information after the 1979 Narrow Water bomb attack which killed 18 British soldiers.
