Teen who boasted ‘we just done a murder’ in a rap video convicted of killing Ibrahima Seck

A 14-year-old who boasted in a rap video ‘we just done a murder’ has been convicted of murdering Ibrahima Seck following a trial.

He had previously pleaded guilty to manslaughter after hearing the strength of the prosecution case, but the Crown Prosecution Service were determined that he would face the full consequences of his actions and continued with the prosecution for murder.

Two other teenagers who encouraged and assisted the 14-year-old, have been found guilty of manslaughter and two women have been found guilty of assisting an offender.

The three boys were together on 8 June 2025, when they had a chance encounter with Ibrahima, his brothers, and friends. The three boys approached Ibrahima’s group and following an altercation, the teenager who would go on to inflict the fatal stab wound asked the 16-year-old for the knife, which was handed over. The trio chased after Ibrahima and his group. It was when Ibrahima slipped and fell to the floor that the 14-year-old with the knife inflicted the fatal stab wound.

Ibrahima was with his brothers and friends, on his way to play football in the park when they encountered the group of teenagers, some of whom had been involved in a number of incidents of animosity towards the Seck family in the preceding weeks, this is thought to be the motivation for the attack.

Two women have also been found guilty of assisting an offender after taking the teenagers away from the scene and providing them with a change of clothes.

Rebecca Macaulay Addison, Specialist Prosecutor for the Crown Prosecution Service in the North West, said:

“This is a tragic case in which another young person has needlessly lost their life as a result of knife crime.

“It was the prosecution case that the three teenagers were acting together. Though just one of the boys inflicted the fatal knife wound, the others had shown by their actions that they acted to encourage or assist him to deliberately inflict serious harm.

“It is deeply concerning to see young people carrying and using weapons on the streets of Greater Manchester and the Crown Prosecution Service will continue to work with our partners to tackle the devastating impact of knife crime.

“Our thoughts are with the family and loved ones of Ibrahima Seck and all those who have been affected by his untimely death.”

Ibrahima had been on his way to play football with his brothers and friends on 8 June 2025, when he came across the other group. A brief altercation occurred between one of Ibrahima’s friends and a boy in the other group.

As Ibrahima ran away, the trio chased him and caught up with him in the car park of the Fairway Inn Public House. Ibrahima slipped on the floor and was fatally stabbed by one of the 14-year-olds.

Those at the scene saw and heard the then 16-year-old hand the knife over to the teenager, at his request, prior to the chase, and the third boy, who was in close proximity, encouraging what was happening.

As Ibrahima sought help from a nearby house, the three boys fled and were driven away from the area.

One of the boys made a video, later recovered by the police, where he boasted “we just done a murder”.

Ibrahima was taken to hospital but was already in cardiac arrest and could not be resuscitated. He was pronounced dead at 6pm.

A postmortem confirmed the cause of death was the wound to the heart which penetrated the full thickness of the front of the heart and led to the cardiac arrest.

Officers stopped Kerri Dobson’s vehicle at 6pm that evening. She was deleting things from her phone as the officer approached, clearly trying to cover up the help that she had provided to the teenagers.

The then 16-year-old and one of the 14-year-olds handed themselves in at Central Park Police Station on 8 June 2025, and the second 14-year-old was arrested at his home address the following day.

At trial, following the prosecution case, the 14-year-old who inflicted the fatal injury, admitted that he had stabbed Ibrahima and caused his death, but he maintained he had not intended to kill him or to inflict serious harm.

Building the joint enterprise case – in it together

If a person assists or encourages another to inflict serious harm, they can face prosecution for their involvement.

Prosecutors must prove to a jury beyond reasonable doubt that each defendant played a part and is therefore guilty of the crime.

They do this by using all available evidence to piece together each defendant’s active role in a crime.

The principal offender that the jury convicted of murder, was making a video bragging that they had ‘done a murder’ soon after the fatal attack.

A person can be found guilty of manslaughter as a secondary party if they can be shown to have acted in a way that encourages or assists the principal offender to inflict serious harm.

We were able to prove in court that there was a history of animosity from two of the teenagers and their associates towards Ibrahima and his family. On 8th June 2025 in a chance encounter the teenagers recognised Ibrahima’s group.

A knife was passed by the 16-year-old to the principal offender in the presence of the third teenager, after which, all three defendants ran after Ibrahima, his brothers and friends and ultimately, Ibrahima was fatally stabbed as he lay on the floor.

All three of the offenders were driven away from the scene.

On 22 December 2025, the jury at Manchester Crown Court, found one 14-year-old guilty of murder, a 17-year-old and the other 14 year old were found guilty of manslaughter and the two women were found guilty of assisting an offender.

Sentencing will take place at a later date.
