Suhail Choudry was found with serious head injuries in Flasby Street shortly after 3.14am on Sunday, February 8.
The 35-year-old father-of-two, whose wife Zara is expecting their third child, died of his injuries on Wednesday (February 11).
Paying tribute to her husband, Zara said: “On the early morning of Suhail’s attack when I received a phone call, I could never have imagined what the coming days would bring.
“Suhail was a father before anything; it was his proudest title and the children were his world.
“Telling your children their daddy has passed away is something no mother should have to do; we will never find peace with the brutality in which he left us.
“I want to appeal today – if you have any information, no matter how big or small, please contact the police.
“Suhail deserves justice, not just for him but for his daughter, son and unborn child.”
Detectives from West Yorkshire Police’s Homicide and Major Enquiry Team continue to appeal for information about the assault and incidents that took place before the attack, which are thought to be linked.
Three men who were arrested in connection with the incident have been released on police bail.
A 42-year-old man who was arrested on suspicion of murder remains in custody.
