Teenager who boasted in a rap video ‘we simply performed a homicide’ after knifing schoolboy to demise is detained for greater than 11 years

A teenager who boasted in a rap video ‘we just done a murder’ after killing a 14-year-old schoolboy has been detained for more than 11 years. 

Ibrahima Seck was fatally stabbed last summer after going to play football with his friends in New Moston, north Manchester. 

He was chased down before being knifed to the heart, but managed to name his attacker before he died in hospital under an hour later on June 8, 2025. 

The killer, who was also 14 at the time and cannot be named for legal reasons, was sentenced today for 11 years and 10 months – the youth equivalent of a life sentence.

During a month-long trial at Manchester Crown Court, the jury heard how he had boasted about having ‘done a murder’ in a rap video. 

Two other boys, who were aged 14 and 16 at the time and were said to have assisted and encouraged him, were found not guilty of murder but guilty of manslaughter.  

They were detained for two years and four months and two years and ten months, respectively. 

The judge refused an application to lift reporting restrictions that would have named the teenage killers.

Ibrahima Seck, 14, was murdered on June 8 last year after being chased down by three other teenagers and knifed to the heart by a 14-year-old boy

Jaime Hamilton KC, prosecuting, told the trial: ‘In the street, after a brief altercation, the 16-year-old boy handed the 14-year-old found guilty of murder a knife that caused a wound which penetrated Ibrahima’s heart.

‘After being handed the knife, all three of these defendants chased Ibrahima. 

‘Tragically, Ibrahima slipped to the floor and the 14-year-old found guilty of murder killed him, assisted and encouraged by the others.’

The court heard how Ibrahima, who was with other boys, had been on his way to play football when he encountered the three defendants that evening, at about 5pm.  

Mr Hamilton claimed that the defendants had been ‘part of a group that had been threatening Ibrahima, his family and his friendship group’. 

He said that the incident began with a fight involving the 14-year-old killer and a friend of Ibrahima on Nuthurst Road. The friend was said to have thrown the first punch. 

Mr Hamilton said footage showed that the fight ended and the two groups began to separate. 

He said that the 16-year-old boy gave the 14-year-old killer a knife, after he asked him to ‘gimme the ting’. 

Ibrahima was chased and after he slipped, the 14-year-old was ‘on him’ in a ‘matter of seconds’, Mr Hamilton said. 

The 16-year-old and 14-year-old assailants also ran up to Ibrahima. Mr Hamilton said that the pair ‘shared a common intent’ with the 14-year-old killer and ‘encouraged him in that fatal act’. 

After leaving the area and going to a house, the 14-year-old killer ‘improvised’ a rap in the aftermath of the killing in which he ‘boasted’ about it. 

In a statement read out on his behalf in court, Ibrahima’s father, Mamadou Seck, said: ‘The people who did this to our son acted with complete heartlessness. I hope they come to understand the immense pain they have caused our family.’ 

Defending the 14-year-old found guilty of murder, Richard Littler KC said that the defendant was ‘genuinely sorry’. 

He added that the boy had told a youth offending worker: ‘No-one deserves to die this way and I deserve a life sentence, because I took a life.’ 

For the 16-year-old boy, Allison Summers KC said that the crime was committed ‘in the heat of a dynamic and fast-moving situation, and done ‘without any thought of the potential consequences’. 

She added that he expressed ‘significant remorse and shame’.

Richard English KC, for the 14-year-old assailant, said the defendant did not have possession of a knife and was ‘some distance’ from the attack on Ibrahima. 

Two women were also on trial, accused of helping the 14-year-old killer and the 16-year-old leave the area and giving them a change of clothing. 

Naomi Heavens, 39, and Keri Dobson, 37, were both convicted of assisting an offender.

Heavens and Dobson were both sentenced to 12 months in prison, suspended for a year. 

The judge, Mr Justice Bright, said that their behaviour ‘made no real difference’ to those responsible being identified. 

The court heard that Heavens told the killer and the 16-year-old assailant to hand themselves in and Dobson didn’t initially know a death had occurred.
