A pair of thugs held a knife to a terrified boy's throat before making him beg for his life while being filmed.
Kyle Robertson, 20, and Declan Graves, 18, demanded the 17-year-old's phone in the shocking incident, which took place on February 17, 2019.
The teen had been lured there by 18-year-old Jessica Simpson, according to Hull Live.
She initially thought the plan was to make him steal booze from a nearby shop.
But things took a sinister turn when the victim refused to hand it over, leading to Robertson thrusting a knife to his throat and Graves holding a blade to his stomach.
Prosecuting, Gordon Stables, told the court: “Graves then took the mobile phone and accessed it. He started deleting pictures and messages from the phone while continuing to hold the blade against him.
“Robertson told him to kneel on the floor and say sorry or he would stab him. He told him to beg. He complied and Robertson then filmed him.”
The thugs then forced the boy into a nearby McColl's shop and told him to go inside and steal alcohol.
Instead, the boy asked staff members for help, telling them what had happened and where he had just been.
Robertson, Graves and Simpson had already fled but were caught up with by the staff member who got them to hand over the phone.
In a victim impact statement read out to the court, the teenage boy said: “I haven’t left the house as I’m scared of seeing Robertson and Graves again.
Hill invited the man to a house in Coventry Avenue, Grimsby, where he was assaulted with the weapon by Sevenoaks and Robertson.
Mr Stables said: “She invited him upstairs and he was met at the top by Sevenoakes who kicked him with force, causing him to fall to the bottom of the stairs. He was then struck with force by a claw hammer by Robertson to the back of his head.
“He [the man] escaped the address receiving further blow to his head as he was chased.”
The court heard Robertson also appeared to be sentenced for a number of driving offences including dangerous driving and driving without insurance after he led Humberside Police officers on a chase through Grimsby and Cleethorpes on February 7, 2019.
The car he was driving had been spotted and checked for insurance and officers gave chase. The 13-minute long chase reached speeds of up to 70mph in 30mph zones.
He was again charged with failing to stop and failing to provide a specimen in April last year.
Mitigating for Robertson, Andrew Bailey told the court the robberies were committed when he was just 18. He said: “He is still very young. You can see he was very immature and perhaps still is.”
Mr Bailey said Robertson has suffered trauma in his life and spent his younger years in care which could explain his behaviour. He said he is determined to address his past behaviour and has already started doing so while remanded into custody.
Mitigating for Sevenoakes, Nigel Clive said the offending was out of character for his client who has no previous convictions. He told how his client did not know about the claw hammer that was used against the victim.
He said: “He is a young man who was once embroiled in drugs but now he cares for his two daughters. His current partner is a credit to him turning his life around. He is a very changed young man.”
Judge John Thackray told the court that the attack on the first victim with a claw hammer was "a very serious example" of wounding.
Speaking about the robbery, the judge said: "The victim was terrorised and was threatened with a knife and you Robertson threatened to stab him. You humiliated him by making him kneel."
Robertson was jailed for seven years and five months for wounding, robbery and two counts of dangerous driving.
Graves was jailed for 18 months for robbery.
Sevenoaks was handed a 21 months sentence for two years for wounding, Hill a 16 month sentence suspended for two years for wounding and Simpson a year long community order for conspiracy to steal.
Graves, Robertson and Simpson were all made the subject of a restraining order against the robbery victim.
