This is the horrifying moment an alleged killer pulled out a samurai sword and called it sexy before hacking a schoolboy to death, a court has heard.

Amateur musician and 'mystic' Marcus Monzo, 37, is accused of killing Daniel Anjorin, 14, who was walking to school in Hainault, east London, on April 30 last year.

Before the brutal attack he filmed himself unboxing the weapon and calling it 'ninja stuff'.

Monzo is also accused of the attempted murders of female police officer PC Yasim Mechem-Whitfield, 35-year-old IT engineer Henry De Los Rios Polina, Sindy Arias and Donato Iwule, who was hit by his van.

In the chilling clip Monzo, dressed in a yellow hoodie and black shorts, showed himself pulling out one of the homemade Katana swords.
