It follows after the Metropolitan Police previously said that the death of 60-year-old Nkiru Chiba could be linked.
Emergency services were first called to Romford station on July 27 this year to reports of a casualty on the tracks and a 20-year-old man was pronounced dead at the scene.
Officers were later called to a home on Bushy Close later that day at around 9pm, to concerns for the welfare of a woman.
Nkiru was found with multiple stab wounds and pronounced dead at the scene.
Days after the investigation, police said early enquiries indicated that the two knew each other.
Detective Chief Inspector Joanna Yorker from the Met’s Specialist Crime Command has now that the Met is “confident” that the two deaths are linked.
She said: “As our enquiries have progressed, we are confident that Nkiru’s tragic death is connected to the death of a 20-year-old man on the train tracks at Romford station earlier that evening.
“The man was known to Nkiru and British Transport Police continue to investigate his death.
“I would like to thank the local community for their support with this investigation so far.
“Our officers are continuing enquiries and we encourage anyone with any information to contact us.”
Anyone with information is asked to call 101 or contact @MetCC on X quoting CAD6914/27JUL.
