A muscleman from Watford said he had to try to do something when he heard a woman screaming and saw her being dragged along the street in the town last month.
Neal Maher, 32, was walking to walk at the NRG Gym at Watford House Lane when he heard the woman crying out for help.
He explained: “I heard her screaming get off me. He was dragging her along by her jacket and using the top of the hood. There were a few people to help – then he pulled a knife out of his pocket.
“I thought ‘This is the last thing I need at 8 in the morning.’ I told him to calm down and she grabbed me and said please help me. I went in between them but he pushed her out of the way and dropped the knife. I used my size then he looked and stared at me. He turned around and walked away and I told her to come with me but she was adamant she was going with him.”
After the pair left the scene, Neal picked up the knife and handed it in to a nearby convenience store before carrying on his journey to work.
He said the people who witnessed the incident were shocked and admitted he should not have let the woman go back.
He added: “Intervening was the right thing to do. I would have had a guilty conscience if anything had happened to her. I didn’t even think about it and was trying to reason with him.
“If there is someone in trouble, I will always try to help. When a woman is screaming and grabs you by the arm, there is no option but to try to do something. I was raised by a strict Irish mum and she would have been disappointed if I had turned a blind eye and walked away.”
