Police want to speak to two brothers over the death of a "gentle" care assistant who was stabbed to death as he held a New Year party at his flat.
Adam Steele, 23, suffered multiple stab wounds after it was thought he stepped in to protect a woman as a row broke out near the gathering in Salford, Greater Manchester. He was taken to hospital but died soon afterwards.
Officers are keen to trace Owen Roche, 21, and Direece Roche, 16, both from the Moss Side area. They also have links to Ashton, Stockport and Salford.
Owen Roche is also wanted after fleeing Manchester Minshull Street Crown Court on Thursday December 16 , where he appeared on an unrelated matter.
Police were called to the junction of Lancaster Road and Orient Road in Irlams o' th' Height following reports of a disturbance at about 5.25am on January 1.
Detective Inspector Steve Keeley, of the Major Incident Team, said: "We have been conducting an extensive and thorough investigation following Adam's murder and are keen to speak to Owen and Direece about what happened that night.
"Owen is also wanted for an unrelated matter and every effort has been made both before Adam's murder and since to locate him.
"If anyone knows where either brother is I would urge them to contact the police."
Mr Steele worked at Pendleton Court care home in Pendleton, Salford, as a senior care assistant and was described by his bosses as a "highly valued and popular team member".
Following his death, his family said: "Adam was a gentle, fun- loving and caring young man whose job was to look after the elderly.
"His whole family is devastated about what has happened and will struggle to come to terms with the loss of such a vibrant, young life."
Two men, aged 18 and 26, have already been arrested on suspicion of his murder and bailed pending further inquiries.
Anyone who sees Owen or Direece Roche is advised not to approach them but call police immediately on 0161 856 1722, 0161 872 5050 or the independent charity Crimestoppers, anonymously, on 0800 555 111.
