A man stabbed a teenager to death after getting into an argument with him at a food and wine store, a court has heard. He said that Mr Perrineau entered at around 3.12pm and asked the shopkeeper if he could sell him an iPhone. The store worker then witnessed Cabdiqaadir, Mr Perrineau and a third man, named as Nijab Rage, arguing before leaving the premises at around 3.17pm. Cabdiqaadir then returned and Mr Rage got into the passenger seat of his car, Mr O'Neill KC said. Mr O'Neill KC said the two men had left Mr Perrineau "bleeding from his chest in the street".
