Officers investigating the murder of 26-year-old Nicola Collingbourne in Letchworth say that they are looking to trace a heavy-set person wearing a high-vis jacket reportedly seen twice in the area on the day before her death.

Ms Collingbourne, 26, was found at her home in Ivel Court on Tuesday evening and was pronounced dead at the scene.

Officers say the person in the high-vis jacket was in the vicinity of Ivel Court at about 8am and again at 12.30pm on Monday.

Originally they reported that the person had been seen on Tuesday, but issued a revised appeal yesterday, Friday, evening.

A 52-year-old woman from Hitchin arrested on suspicion of murder on Thursday remains in police custody.

Officers from the Beds, Cambs and Herts major crime unit are appealing for further information.

Det Insp Fraser Wylie said: “Our enquiries are continuing and I am appealing for anyone with any information to come forward.

“I am particularly keen to hear from anyone who remembers seeing a person of large build wearing a high-vis jacket in the vicinity of Ivel Court, Hadleigh and Hamonte, at around 8am and again at 12.30pm.

“The area would have been busy around these times so I believe a number of people may have seen this person.”
