A man who was killed on his way to work in the early hours was attacked by robbers who used an "extreme and sickening level of violence", detectives have said.
Choudhry Zishan, the married father of a young child, had left his home in Eastleigh, Hampshire, to start work at a newsagent's shop when he was attacked at about 4.30am yesterday.
A post-mortem examination carried out at the Royal Hampshire County Hospital in Winchester by a Home Office pathologist gave a cause of death as trauma to the head.
Detective Superintendent Paul Barton, of Hampshire Police, said: "It would appear that Mr Zishan had just left home for work when he was attacked.
"I believe this was a robbery where the level of violence was extreme and sickening.
"I am still asking for the public's help in looking for items that may have been discarded. In particular I am looking for some shoes worn by one of the attackers and possibly a light-coloured top.
"If you find any items matching that description, please call us straight away."
Two men, aged 25 and 22, have been arrested on suspicion of murder and detectives have been granted an extension of custody to allow further time for questioning.
A police spokeswoman said: "The men were arrested in Monks Way, Eastleigh, and police have also searched an address in George Wright Close, Eastleigh. Residents local to those areas are asked to check their gardens and bins for the items described."
Flowers have been left outside the Newsmarket shop where Mr Zishan worked.
