Nicholas Brandram, a 44-year-old banker, was arrested in June on suspicion of being the "Putney Pusher"—the person responsible for pushing a woman into the path of a bus on Putney Bridge in 2017. He was released under investigation in early September and found dead on 15 September. His family claims there was no credible evidence linking him to the crime and contends that his death resulted from the psychological toll of the investigation and subsequent media coverage.

Brandram's family stated that police found no forensic evidence placing him at the scene or matching him to CCTV footage, yet police proceeded with arrest rather than inviting him for interview and subsequently released information to the press. Following his arrest, officers also charged him with possession of Class A and Class B drugs. Brandram, a former director at HSBC's private bank who was suspended after his arrest, was a descendant of Princess Katherine of Greece and Denmark. The Metropolitan Police has referred the case to the Independent Office of Police Conduct (IOPC) as required when deaths follow police contact, and the original investigation remains ongoing.
