A Deliveroo rider was stabbed outside a north London McDonald’s while trying to stop a thief stealing his bike, it is believed.

The cyclist, in his 20s, was attacked on Fore Street in Edmonton, on Saturday afternoon.

Multiple bystanders rushed to his side and several people tried to deliver first aid to him.

He was taken to hospital but his injury is not thought to be life-threatening.

A 19-year-old man was arrested at the scene, on suspicion of causing grievous bodily harm.

Footage circulating social media shows a man in a Deliveroo jacket, lying on the road with the company’s signature blue box next to him.

Another man can be seen pinned to the ground by security while someone else in a white shirt and black trousers appears to be holding a knife as he walks through the crowd.

Several people who posted the footage online said the victim was hurt after someone tried to take his bike.

The Metropolitan Police has not confirmed this and has not commented on the clip.

The force said: ‘Police were called at 16:27hrs on Saturday, 1 July to Fore Street, N18 following reports of a male stabbed.

‘Officers arrived and found a large crowd who were providing first aid to the man, who is believed to be aged in his late 20s.

‘He has been taken to a north London hospital; we await an update on his condition.
