Plumber who was first on scene of London stabbing reveals agony of one of four 'random' vict
Crime scene: Plumber Roger Blackman (pictured right) helps police officers at the scene of the fourth London stabbing
A plumber who was first on the scene of one of the North London stabbings has described how he 'saw blood pouring out of the back' of one of the four victims, who shouted: 'Why has this happened to me?'
Roger Blackman rushed to help a man who was knifed on the street on Sunday morning in the fourth act of violence in a 14-hour rampage in Edmonton, London.
Police said a lone attacker had carried out the four attacks on Saturday and Sunday, apparently targeting 'random' victims who were 'alone and vulnerable' and leaving one of them, a 45-year-old woman, fighting for her life.
Detectives have made two arrests but the attacker, described as a tall, skinny black man wearing a hood, may still be at large.
Police promised 'enhanced and dedicated police activity around the clock' to keep the area safe but have warned the public to be vigilant.

'I saw the guy turn around and run off, he was literally about 10-15 feet away from where I was. I was in the back of my van so I'm always aware of what's going on around me.
'The victim was screaming, oh my God, oh my God, why has this happened to me. There was blood pouring out of his gash. It was a great big gash, about a three-inch wound.
'I was visiting my mum for mother's day. You hear about it in the papers and now it's happened in front of your mother's house. It does make you wonder, it makes you think about going out.'
