Rasheed Rahman, a 19-year-old Sudanese national, fatally stabbed Mark Carroll, a 55-year-old grandfather, in an unprovoked attack in a London park on April 10, 2024. Rahman had been released on police bail twice in the days prior, despite a record of violent behavior, including assaults on the public and burglary. He attacked Carroll while the latter was enjoying a day out with a friend, inflicting a fatal stab wound that severed his aorta. Following the incident, Rahman threatened two additional individuals before being apprehended by police. The Metropolitan Police is now reviewing their interactions with Rahman to determine if preventive measures could have been taken. Concerns have been raised by mental health charities regarding the adequacy of support for individuals like Rahman, who had a history of mental health issues and drug psychosis. Carroll's family mourns the loss of a kind and generous man, emphasizing the need for better mental health care and public safety measures.
