Ally Evans was described by her partner, Shaun Mathieson, as “a kind hearted, bubbly, decent person.”
Ms. Evans collapsed and died in the Coral bookies, on York Road, after an incident on a Number 7 bus at around 10.45am on Tuesday, 13 October.
A Home Office post-mortem examination has since taken place, with additional specialist pathology examinations being undertaken to establish the cause of death.
A 26-year-old woman has been arrested on suspicion of manslaughter and, following questioning in police custody, has now been released on conditional bail while enquiries continue.
Detective Chief Inspector John Bonner, from Cleveland Police’s Homicide and Major Enquiry Team (HMET) said: “The investigation remains ongoing and a number of lines of enquiry are being pursued to establish the circumstances surrounding the woman’s death. As part of those enquiries, I am still keen to hear from passengers who were travelling on the Number Seven bus or witnessed an altercation between two women. In particular anyone who attempted to intervene during the altercation.”
He added “I would also encourage anyone with information, CCTV, mobile phone footage, or any other material which may assist the investigation to get in touch. You can do this by calling 101 or visiting our website quoting reference number 205074.”
