Describing the knifeman as wearing a fleece mask.

The worker, who did not want to be named, described the scene telling PA news agency: "I saw two or three teenagers on bicycles and they were following this middle-aged man, around 40 to 50, who was smartly dressed.

“The next thing I saw was this teenager grabbing this guy, this middle-aged man. Things escalated so quickly.

“Pedestrians got involved and they were trying to help the middle-aged man. I heard lots of screams and shouts.

“The next minute, a man on a white moped saw what happened and jumped off, and got himself involved.

“There was a fight with these teenagers. Out of nowhere, the guy on the moped got stabbed.

"The middle-aged man was already on the floor at this point after he got stabbed and another pedestrian got hurt too, his head was hurt.

“The teenagers then just took off.”

Elsewhere, Charlotte Wright an administrator that works nearby the scene said she felt scared after hearing about the stabbing in Bishopsgate.

She was walking to work when she saw the emergency services rushing to the scene.

Ms Wright told the PA news agency: “I was walking into my office at about 9.45am and saw a load of ambulances coming by me, which was unusual.

“I heard a bunch of police cars too. It wasn’t until it got close to my building and I saw all the blue lights and I realised that’s where they were heading to.

"There was a crowd around the area. It seemed like a sombre atmosphere, there was a lot of chatting and confusion. My brother then sent me an article explaining what had happened, and I realised what I saw.”

She added: “When I got the text from my brother, I thought ‘Oh my God, that’s way more serious than I could have imagined’.

“I feel a bit apprehensive and scared coming out to get my lunch, but also pretty secure and safe.

"I know London is a very busy city and I know that if anything were to happen, unfortunately like the guys that stepped in during this incident, there are heroes willing to do that.”
