John McMahon was jailed for three and a half years for assault causing harm at Dublin Circuit Criminal Court, reported on 21 January 2015.

The attack happened at a methadone clinic on Spring Garden Lane, Dublin, on 1 December 2012.

Christina Joyce needed emergency surgery after a blade severed an artery in her arm, leaving visible scarring and lasting loss of feeling in two fingers.

McMahon pleaded guilty to assault causing harm and possessing a sharply pointed blade, after CCTV and a recovered Stanley-type blade linked him to the attack.

Judge Martin Nolan said the attack caused serious disfiguring scars and backdated the sentence to McMahon’s remand in December 2012.
