Murder squad detectives investigating the death of a 33-year-old woman have issued a picture of her in a bid to piece together her final hours.

Police believe she was driven to hospital hours before she was found with serious head injuries at her Bradford home.

They have urged anyone who saw mum-of-three Samantha Warren outside Bradford Royal Infirmary at about 5.30pm last Thursday to get in touch.

She is understood to have been travelling in the front passenger seat of a dark-coloured Citroen, driven by an Asian man, which stopped, before being driven away with her inside.

Miss Warren was discovered later on Thursday with extensive head injuries at her home in Libbey Street, Manningham.

She died in hospital late on Sunday night.

Detective Chief Inspector Jon Morgan, who is leading the police investigation, said: “In order to establish the full circumstances which led to her death, we need to hear from anyone who was outside the hospital and that saw her during this time.

“In particular, we are keen to speak to a man who is described as white, with short brown hair, wearing blue jeans and a dark coloured jacket, as he may be able to help us in our investigations.”

A 43-year-old man, who has been charged with Miss Warren’s murder, was remanded in custody on Monday after making his first appearance at Bradford and Keighley Magistrates’ Court.

Santosh Kumar, of Crosley Wood Road, Bingley, is also charged with wounding Miss Warren on Thursday, April 26.
