Chilling footage reveals the moment a coked-up delivery driver ran through London's street half naked and wielding a huge kitchen knife after stabbing a man to death.
Nicholas Foy had snorted four-and-a-half grams of coke in a 24-hour drink and drugs binge before he ran up to nuclear scientist Laurent Volpe, 49, and plunged the large knife into his stomach, which passed through Mr Volpe's liver.
The 39-year-old then - who was jailed for life yesterday - then began threatening passers-by yelling "do you want some?"
He was picked up on CCTV running through Eltham, south east London dressed only in his boxers just moments after the horrific crime.
Mr Volpe, who was on a two-week holiday with his wife Cecile Chapais and their two children, collapsed at the scene in shortly before 7pm on August 11 last year.
