A former detective inspector has revealed which criminal 'frightened' him and says she would kill again if she was ever released.
Steve Keogh worked for the Metropolitan Police for over a decade and spent time working on the force's Anti-Terrorism unit before retiring from his position last year.
There's no doubt that he's been in contact with some of the country's most evil criminals, but says it was female double murderer Nicola Edgington that made him feel unsafe during her arrest - a feeling he'd never experienced before.
Speaking to The Sun, he said: "She is without a doubt, not including terrorists, the one I have no doubt in saying if she was released she would kill again.
“She frightens me to be honest, I have never felt unsafe arresting anyone or confronting them but she is frightening.”
Nicola Edgington brutally murdered Sally Hodkin, 58, two years after she was released from a secure hospital for killing her own mother.
The attack happened hours after she warned an A&E receptionist she would 'kill someone' then absconded through a door which should have been locked.
The grandmother was repeatedly stabbed with a stolen butcher’s knife on the morning of 10 October 2011 after Edgington, then 31, freely walked out of Oxleas House mental health unit in Greenwich.
After leaving the unit, she got a bus to Bexleyheath, south east London, and went to an Asda store where she bought the knife used to attack Kerry Clark, who fought her off at a bus stop.
She then fled and stole a knife from a butcher’s shop before attacking Mrs Hodkin, who was on her way to work.
DI Keogh went on to speak about what he witnessed: "When she was assessed she showed high levels of narcissism. She had an extremely high sense of her own importance and was completely lacking in empathy.
“The psychologist said that she killed because she was angry, narcissistic, for attention and no good reason.
“She killed Sally Hodkin because she wasn't getting what she wanted and that made her angry.
“All she wanted to do was show everyone that she should have been listened to. It was the same with her mum's killing.
“I have no doubt that she would do the same again if she felt people weren't taking her seriously.”
Edgington was jailed for 37 years in 2013 for the murder of Mrs Hodkin and attempted murder of Kerry Clark.
