From The Sun:

Witness Felipe Carvalho, 31, was riding home from Islington on his moped when he saw two men arguing in the street where houses cost £1million.

He told the Sun Online: "A man had a large rucksack on and I saw another man shouting at him saying 'give me my phone back'.

"The man then pulled a huge knife out of his bag - it was about 60cm long.

“He showed it to the other guy and seemed to be threatening him. I shouted ‘leave it, it’s just a phone’ but they kept on arguing."

He added: "I tried to help. It’s so sad that a man has lost his life over a mobile phone."
