Clockwork Orange gang jailed for ‘happy slapping’ killing

SHE looks like a teenage angel, but 16-year-old Chelsea O’Mahoney was the personification of evil as she filmed friends stamping on a man’s head in one of several so-called “happy slapping” attacks on randomly picked victims.

Yesterday, O'Mahoney was given eight years behind bars for her part in five random attacks on eight innocent victims.

O'Mahoney was part of a Clockwork Orange-style gang of youths who took "pleasure" from the infliction of pain.
