Dale Martin, 21, was killed on Stenson Road in Derby on June 15, 2025, after being dragged from his car and stabbed by a group armed with swords, machetes, and Rambo knives—types of weapons typically associated with violence. Footage from a nearby camera shows a group of individuals wearing balaclavas, or face coverings, ambushing Martin. They had pursued him following a "tit for tat" dispute, meaning a cycle of retaliatory actions, between two rival groups. The attackers shouted "kill him, kill him" before carrying out what was described in court as a "brutal, sustained, and planned" attack that left Martin to die. Six men from Derby were found guilty of killing Martin after a four-month trial at Loughborough Crown Court. Jayden Mannion-Roberts, 26, was convicted of murder, while Keenan Hamblett, 27, Ki Grant-Finlayson, 23, Kayin Holmes, 25, Kelci Thompson, 19, and Shaylon McCalla, 27, were all convicted of manslaughter. One of the accused, Carlus Grant-Finlayson, 18, was found not guilty of murder, despite having been charged with the crime. The court was told the attack was part of a long-standing feud between two rival groups. Martin was in a Renault Megane when the attackers blocked his path using electric bikes. They struck him in the head, chest, and back after he fell to the ground trying to escape. CCTV footage showed the group riding their bikes before and after the attack, and body-cam recordings captured two of the attackers being arrested in their underwear at home, while others were caught at London Gatwick Airport. Police also released images showing blood splattered on Martin's car following the attack. Detective Sergeant Chris Wright of Derbyshire Police said the attack was "brutal, sustained, and planned," with the perpetrators armed and intent on killing Martin. He noted that the victims' family now knows who is responsible for their loved one's death, and while nothing can undo the trauma of losing a son, brother, and friend, they will now see those responsible face the consequences of their actions. The men are set to be sentenced at the same court on October 1.
