which together with drink had resulted in "a psychological perfect
storm", a court heard.
But a judge ruled the Tenterden teenager's attack was so
serious he had to be locked up for four years.
North, pictured left, had earlier been involved in a
bust-up when a close friend punched him to prevent
more trouble - and then put him in a car to cool down.
Raging North took that as "an act of betrayal" by his
19-year-old friend and, when he came to apologise, he

shied away from parties because he didn't like being in the public
eye but on this occasion threw himself in with gusto,
