A man in his 20s was stabbed with a machete in an appalling daylight brawl outside an estate agency in London – as frightened staff hid inside and frantically called the police.

In a video shared widely on social media, one man who appears to be holding a machete, tries to grab another man’s bag.

The fight, which took place outside Benham & Reeves on Plumbstead Road, Woolwich, yesterday – was filmed by horrified passengers on a bus passing by.

Terrified employees inside the estate agency were trapped inside their offices while the horror attack unfolded.

One told MailOnline: “I was so scared. I was shaking.

“I have never witnessed anything like that before. The size of the knife – I have never seen one like it.

“I called the police – everybody was calling them.”

She added: “There were a group of lads robbing another – probably about four or five.

“One had a huge machete and they were scuppering outside our office.

“I am not sure if they managed to get the bag in the end. They then ran over to the estate and it looked like they might have hurt his leg.”

No arrests have yet been made.

A spokesperson for the Metropolitan Police said: “Police were called at 4.07pm on Monday, May 13 to reports of a group of males fighting – some allegedly seen to be armed with knives – on Plumstead Road, Woolwich.
