A Bangladeshi man suspected of the fatal stabbing of a mother who was pushing her baby in a pram along a high street entered the UK on a student visa, it has emerged.
A nationwide manhunt is under way for Habibur Masum, 25, after a 27-year-old woman was attacked in the Westgate area of Bradford on Saturday.
West Yorkshire Police said Masum may still be armed and warned members of the public not to approach him.
