Lisa Dean was leapt to the rescue as the defenceless victim and her young son were caught up in a brutal attack, with the man landing up to 30 punches on the woman.

Lisa, 41, looked on as the man launched the vicious assault at a cash point outside John Lester Hair Design in Globe Road, Stepney Green, after accusing the woman of cutting in the line.

“The man was very agitated,” she said. “I said ‘he’s going to do something silly’ – I could see it.”

He then launched the attack on his victim, prompting a timely intervention from feisty Lisa.

“I ran out of the shop to get him off her and pushed him away”, she said. “I’ve done self-defence classes so I can handle myself!

“I’ve never seen violence like it. They were having a proper fight - he was punching her like she was a man.

“If I didn’t jump in he would have carried on. He was going for it.”

After the man fled from the scene with another driver, Lisa brought the mum – who asked to remain anonymous - into the salon, before she was taken to the Royal London Hospital for treatment.

Police confirmed a 33-year-old man had been arrested and bailed until March in relation to the incident.
