A teenager who was released on police bail twice—allowing him to commit a brutal murder—has been sentenced to life in prison. Rasheed Rahman, then 19, stabbed Mark Carroll, 55, in the back with a five-inch kitchen knife in a small London park on April 10, 2024. The attack was described by the judge as "shocking and cowardly." Rahman, who had no prior relationship with the victim, fled the scene still holding the knife, leading to a lengthy manhunt. He also threatened two other people with the weapon before being caught. Rahman, a Sudanese national who claimed he entered the UK illegally as a child, had been arrested twice before the murder and released on bail. In the months leading up to the attack, he had stabbed another man, Iulian Cavaliuc, in east London, but police were unable to locate him due to delays in reviewing CCTV footage. The Metropolitan Police has since launched an internal investigation into whether police could have prevented the murder by acting more quickly on Rahman’s known history of violence. Judge Dodd sentenced Rahman to a minimum of 24 years and 59 days in prison at Wood Green Crown Court, calling the attack "a random, unprovoked attack" on an innocent man. The judge said Rahman is a "very dangerous young man" and that the murder left Carroll’s family "broken and grieving." Carroll’s daughter, Danielle Morley, was 19 weeks pregnant when she learned of her father’s death. She described him as a kind and loving man who was simply enjoying time with friends when he was attacked. Another daughter, Ayisha Carroll, has been diagnosed with post-traumatic stress disorder (PTSD) and continues to suffer from flashbacks and emotional distress. She said the murder changed her perception of the world and left her afraid for her loved ones. Rahman had a history of violent and illegal behavior. Before the murder, he had attacked people on a canal towpath, smashed a window with a brick to break into a church office, and was arrested for possessing a drug and a sharp object. He had also been granted temporary leave to remain in the UK after an asylum application in 2023. His defense argued that Rahman had experienced severe trauma in Sudan and Libya, including witnessing the murder of his sister and enduring enslavement and torture. However, the judge noted that Rahman was not currently suffering from a severe mental illness and that there was no independent evidence to support claims about his traumatic background. The court found that Rahman’s age and lack of intent to kill were the only mitigating factors, but they did not lessen the severity of his crime.
