Police have launched a manhunt after a mother pushing her baby in a pram was fatally stabbed.
West Yorkshire Police confirmed Habibur Masum, 25, is wanted over the attack.
The attack took place in the Westgate area of Bradford at 3.21pm yesterday.
A 27-year-old woman, who suffered multiple stab wounds, subsequently died in hospital.
The force claimed the woman was with her baby at the time of the attack, adding people should not approach Masum.
West Yorkshire Police claimed he was known to the victim but have not confirmed their relationship.
The suspect was described as an Asian man with a slim build.
He was pictured on CCTV wearing a duffle coat with three large horizontal lines of grey, white and black, light blue or grey tracksuit bottoms with a small black emblem on the left pocket and maroon trainers.
A witness later claimed the suspect was wearing a grey hoody with the hood up.
Det Ch Insp Stacey Atkinson said: “We have had significant resources following up a number of lines of inquiry to locate Habibur Masum but at this time his whereabouts are unknown.
“I would urge anyone who does see him not to approach him but to call 999 immediately.”
He is also believed to have links to the Burnley and Chester areas.
Following the attack yesterday, Atkinson also said: “This is a shocking incident that has happened in broad daylight in a busy area of Bradford and been witnessed by a number of people.
“A young woman has lost her life in the most awful circumstances, and we have extensive enquiries ongoing to locate and arrest the man responsible, who is understood to be known to the victim.
“We know this incident will understandably cause concern in the local community, and I would like to reassure the wider public that we are working tirelessly to investigate this horrendous crime and bring the person responsible to justice.
“To help us with this we are urging anyone who was in the area who may have dashcam footage or seen or heard something, however small it may seem, to please come forward.
“A scene remains in place which includes some road closures and I thank the public for their patience while we conduct our enquiries.”
