Four men have been arrested in connection with the murder of a 22-year-old man in Leeds.
Thomas Ball, 22, of Woodview Terrace, Beeston, was found with serious injuries at an address on Headingley Lane on Monday. He died in hospital a day later.
A post-mortem examination found Mr Ball died as a result of an assault.
West Yorkshire Police said two men aged 20 and two aged 21 had been arrested on suspicion of murder.
A statement from Mr Ball's relatives released by police said he was devoted to his one-year-old son, Tyler.
"He will be in our hearts always and never forgotten," the statement added.
