Two people have been arrested on suspicion of murder after a man was found stabbed to death in a garden.
The victim, 31-year-old Nigerian national Adebayo Adeniran, was found outside a house in North Avenue, Coventry, at around 9.30am on Thursday.
West Midlands Police said a 31-year-old man and a 30-year-old woman were arrested in the early hours of this morning.
A post mortem examination revealed Mr Adeniran, who was known locally as Patrick, died as a result of multiple stab wounds.
Detective Chief Inspector Matt Markham said: "A young man has been attacked and left for dead in the most awful of circumstances and our thoughts are with Mr Adeniran's family at this difficult time.
"We need to bring the people who committed this dreadful act to justice.
"I want to hear from anyone who knows anything about what happened and I am particularly keen to establish Mr Adeniran's movements on Wednesday evening.
"He was black, with short black hair and around 5ft 9ins tall. We know he was wearing a pink shirt underneath a blue jumper, jeans and a rucksack and that he was last seen alive at around 7pm on Wednesday night.
"Were you in the Walsgrave Road, Binley Road or Far Gosford Street areas of the city between 6pm and 10pm on Wednesday night? Can you remember seeing someone matching Mr Adeniran's description?
"We suspect the victim may have been in the company of other people and I would ask anyone who was in the area to cast their minds back and think carefully about whether they can assist with our inquiry.
"The smallest piece of information could be crucial to this investigation so I would ask anyone who has any information, regardless of how insignificant they think it may be, to call us and let us make that decision."
Police urged anyone with information to call Force CID on 101 or Crimestoppers anonymously on 0800 555 111.
