Mikey Allsop was just 17 when – after seeing his father, Dean Allsop, attacked by Jamie Crosbie – he ran to grab a knife and hit the killer with it in an attempt to stop the attack on his dad.

But a spokesman for Norfolk Police later confirmed that Mikey would not face any further charges following the incident. Miss Newell said: “The relief when they revealed there would be no further action – it was just one less thing to worry about.”
