Three individuals involved in a violent gang-related stabbing in Camden, North London, have received significantly longer detention sentences following a successful referral by the Solicitor General. Kye Regis, Celyse Knight, and Khalil Haidara, who were convicted of attempted murder, saw their sentences for this charge increased by four, five, and four years respectively by the Court of Appeal on Thursday, 11 June 2026.
The case was brought before the Court of Appeal under the Unduly Lenient Sentence scheme by Solicitor General Ellie Reeves KC MP. The court heard details of the brutal attack that occurred on 1 November 2024, when the three members of the Agar Grove gang targeted rival gang member Omar Greaves. All three attackers were armed with knives, pinning Mr Greaves down before stabbing him five times. Mr Greaves required life-saving surgery at hospital but ultimately recovered from his injuries.
The court also considered further violent acts committed by Regis and Knight. On 9 November 2024, prior to their arrest, they assaulted another rival gang member. Subsequently, while in custody awaiting trial, Knight attacked another prisoner with a metal bar on 30 December 2024. These incidents highlighted a pattern of continued violent behaviour before and during their detention.
Initially, at Central Crown Court on 19 December 2025, Kye Regis was sentenced to 15 years’ detention for attempted murder, possession of a bladed article, and assault occasioning actual bodily harm. Celyse Knight received 12 years’ detention for attempted murder, possession of a bladed article, assault occasioning actual bodily harm, and unlawful wounding. Khalil Haidara was sentenced to 13 years’ detention for attempted murder and possession of a bladed article.
Following the Solicitor General's referral, the Court of Appeal adjusted these sentences. Kye Regis's sentence for attempted murder was increased to 18 years, leading to a total detention period of 19 years. Celyse Knight's attempted murder sentence rose to 14 years and 6 months, with other sentences adjusted to run consecutively, resulting in a total of 17 years’ detention. Khalil Haidara's sentence for attempted murder was increased to a total of 17 years’ detention.
Solicitor General Ellie Reeves KC MP commented on the decision, stating that gang-based violence has a devastating impact on public safety. She welcomed the court’s decision, emphasising her commitment to supporting the government’s efforts to tackle knife crime and gang violence in towns and cities across the UK.
