Finance student Henry Nowak, 18, was on his way home from a night out when he was attacked by stranger Vikrum Digwa, 23, with the eight inch 'Shastar' blade.

Prosecutors said Vickrum Digwa, 23, was 'skilled' with blades when he came to murder Henry Nowak, 18, having trained with weapons since he was 12.

Vickrum Digwa, 23, said he had given 'demonstrations' with Sikh weapons since he was 10 years old and admitted that he 'did know how to use them'.
