A woman has described how she chased two youths through Woolwich's General Gordon Square after they stabbed a man in the back.
Witnesses claim trouble broke out in the busy square on Sunday (July 6) after the "boys" had argued with their 26-year-old victim at Woolwich Arsenal station.
One man claimed the victim was stabbed with his own knife after grabbing one of the youths by his neck.
But another wtiness said: "The man was really struggling to get away. They grabbed at his clothes but he wanaged to run. He was obviously in a desperate state.
"He must have kicked them and broken away from them. As he ran I saw another boy chase him and he had a knife in his hand.
"Afterwards they ran staright over the road again and down a side road."
A woman, who did not want to be named, told News Shopper she had pursued the stabbers but they managed to get away from her.
She said: "I chased the two boys across the square to a black gate which they jumped over and removed their clothing.
"I am shocked that they have not been caught as they obviously know Woolwich well to know where to run and also where they would have come out. There is a CCTV camera there. I would definitely recognise both of them again."
Greenwich police are appealing for witnesses to the attack which happened in General Gordon Square, near Greens End, at 4.50pm.

Police are asking anyone who was in the area and that may have seen anything to contact them.
