Detectives investigating the fatal stabbing of an elderly motorist have released her identity.
Mary Evans, who was known as May and had only recently changed her surname from Olloman, died after being seriously assaulted in Trent Road, Luton, just after 3pm yesterday, Bedfordshire Police said.
Mrs Evans, 70, who lived in Liddle Close, Luton, re-married only six weeks ago.
Members of the public detained a man, who is in his 50s and known to the victim, before officers arrived.
He was arrested on suspicion of attempted murder and taken to Luton police station for questioning and subsequently re-arrested on suspicion of murder. He remains in custody.
Family liaison officers continue to support Mrs Evans's family and Detective Chief Inspector Jonathan Hutchinson of the major crime unit (MCU) is keen to trace anyone who may have relevant information.
He said: "This was a terribly distressing attack on a defenceless woman who had recently married and should have been enjoying life with her family.
"We are in the process of trying to piece together exactly what happened prior to the stabbing and although we have arrested a man in connection with this incident, this inquiry is not solved and we do want to hear from anyone else who can help with information about what happened.
"You may have been walking past just before or after the incident, or saw something or someone that was unusual, as you drove or walked along Trent Road.
"You may have already dismissed this information as insignificant or thought that the arrest of a person made it less important to us.
"Please don't assume that someone else has told us, or that we already know. Please come forward if you were in the area so that we have the fullest picture possible to help us complete this inquiry."
Anyone with information relating to this investigation is urged to contact officers from the MCU in confidence on 101, or text information on 07786 200 011.
