Nicholas Brandram, a 44-year-old private banker, died whilst under investigation by the Metropolitan Police for the Putney Pusher attack, in which a woman was pushed into an oncoming bus on Putney Bridge in May 2017. His sisters have accused the Met of negligent handling of the case, claiming that delays in conducting a DNA test significantly worsened his mental health and contributed to his death. The family insists he was innocent and claims the investigation lacked credible evidence against him.

According to his sisters Alexia Hicks and Sophie Voelcker, Brandram offered to pay privately for a DNA test two months before his death to accelerate the investigation, but police declined, promising results within four weeks. The test remained incomplete when Brandram died, with officers later unable to provide a completion date. Brandram had been released on bail but remained under investigation; he was also arrested for drug possession and suspended from his role at HSBC's private bank. His family states there was no forensic evidence linking him to the crime or placing him at the scene.
