This is the chilling moment a balaclava-clad teenager fled the scene after stabbing an 18-year-old man through the heart with a Rambo-style knife.
Noah Smedley was fatally stabbed after meeting up with a group of teenagers, including his killer Charles Hartle, 17, in the evening on December 28 last year.
Hartle who had an ‘unhealthy interest in knives’ went with friends to buy cannabis from Noah that evening.
CCTV footage from the evening shows the moments before the stabbing, with the teenagers stood together on Rose Avenue in Ilkeston.
Hartle was then caught on video holding the knife which he used to stab Noah Smedley, which he had kept hidden in his tracksuit bottoms.
He was then seen running away from the scene on the nearby Kedleston Drive.
Noah staggered away but collapsed moments later, police said.
Despite the efforts of passers-by and medics, he died at the scene.

Hartle was seen running along nearby roads as he continued to make his escape.
He was caught on CCTV on a residential road, where he can be heard making a phone call, in which he tells someone to take him off speaker phone.
Hartle was caught running through several more streets before he took a taxi from Ilkeston to Derby.
In the hours after Noah’s murder, Hartle disposed of his clothing, the murder weapon, and phone before eventually handing himself in at Ilkeston Police Station.
Bodyworn footage from the police station showed Hartle as he was arrested.
Hartle, now 18, of Station Road, Stanley, was found guilty of murdering Noah after a two-week trial at Derby Crown Court.
Hartle’s friends, were unaware of his intentions when the group met up with Noah and provided eye-witness testimony in the case.
They said that all were in good spirits at the meeting.

They explained how Hartle had initially stayed slightly back from the rest of the group and didn’t acknowledge Noah.
He then stepped forward, as Noah went to give him a ‘fist-pump’ goodbye, pulled a balaclava over his face, grinned, and pulled a Rambo knife from his waistband before plunging it into the 18-year-old’s chest.
Hartle, who liked to go by the nickname ‘Lil Cee’, then fled and went to meet his girlfriend at a house party.
Witnesses at the party saw him confess to her and produce the knife – which has never been recovered.
Hartle travelled to Derby city centre in an attempt to distance himself from the scene after leaving the party.
Jurors at Derby Crown Court heard that Hartle and his friends ran from the scene leaving Mr Smedley ‘staggering and bleeding profusely’.
The knife penetrated the right ventricle of Mr Smedley’s heart and his left lung causing internal bleeding and his lung to collapse, the prosecutor said.
Prosecutor Mr Langdale told the court: ‘The defendant raises the idea of self-defence claiming to the police he had recently been threatened by others with knives. As a result of that he decided to take this knife out.

‘The Crown say this is an entirely false account, instead it was the defendant who routinely carried a Rambo knife… and did so for the kudos and bravado.’
The prosecutor said Hartle carried the weapon to show others he was a ‘big man’.
CCTV of the group was shown to the jury, including the moment Mr Smedley was fatally stabbed with a knife described to be ‘eight to nine inches’ long.
Detective Constable Emma Barnes-Marriott, officer in the case said: ‘Noah was an unarmed teenager, who was simply meeting with friends on the night Charles Hartle decided to end his life.
‘Noah did not threaten Hartle and showed nothing but friendliness towards him that evening, and yet he was brutally murdered.
‘Charles Hartle is a callous and calculating young man, who has shown no recognition or remorse for taking another teenager’s life.
‘He carried a knife with the intention to use it, over what appears to be a petty disagreement that only he was aware of, and a sense of bravado.
‘I’d like to thank Noah’s family for their support during our investigation and the trial.

‘No family should have to go through the ordeal of losing a loved one, especially at such a young age, and to have to relive their last moments at trial is an additional blow that Hartle could have spared them from.
‘Instead, despite overwhelming evidence, he remained silent and refused to take responsibility for Noah’s murder.
‘I know that nothing will bring Noah back but hope that today’s verdict has provided his family with some comfort that justice has been done.’
Hartle will be sentenced at Derby Crown Court on 22 August.
