According to witnesses, the incident involves a man who was stabbed in the leg.
One bystander said “This is life in London these days. Keeps happening like it’s not big deal.
“Back in my day we used to have a fist fight and move on. Now they carry knives.
“It’s all very well stabbing someone in the leg but if they get and artery you might bleed to death.
“The mayor and authorities need to get a grip of these things.”
