TWO maniac muggers were last night behind bars for a terrifying knife-point robbery on two revellers who were walking home after a night out.

Simon Davidge and Hayley Flynn threatened to stab their victims if they did not hand over valuables and withdraw money from a cashpoint machine.

Davidge – jailed for four years in 2005 for two similar street robberies – was locked up yesterday for five-and-a-half years at Teesside Crown Court.

Flynn was jailed for four years after being told by a judge: “The threat of the knives being used was no doubt extremely traumatic for these young men.”

The court heard how the victims – aged 20 and 21 – had been for a night out in Stockton and were assaulted at an underpass near the town centre.

One had a knife held to his face by 36-year-old Davidge after he tried to fight back, and was warned: “Try that again, and I’ll cut you like a cat.”

Flynn, 26, threatened to castrate the other young man and rifled through his pockets and took his mobile phone, passport and wallet, the court was told.

The victims were frogmarched at knifepoint to an ATM and warned they would be stabbed unless they handed over their pin numbers for their cards.

Yvonne Taylor, prosecuting, said one of the young men broke free and ran off after being told: “Your codes better be right. Your lives depend on it.”

Andrew Turton, for Flynn, said she was taken to hospital after her arrest because police were so concerned about the amount of drugs she had taken.

“She can’t explain her actions other than the simple effect a cocktail of drugs had upon her changed her behaviour,”

Mr Turton told the court.

“She does not like the way she acted. She understands the behaviour has impacted on her family and the victims, and has grave regrets about that.”

James Kemp, for Davidge, told Judge Peter Armstrong: “He is extremely remorseful and disgusted by his actions.

He acknowledges what he has done.”

Davidge, of St Pauls Street, and Flynn, of Trent Street, both Stockton, admitted two charges of robbery and two of kidnap at an earlier hearing.

The judge told them: “You produced knives and put these two through an ordeal which no doubt will have lasting effects upon them.”
