Zbigniew Michniewicz, a man believed to have been murdered in Greenford, west London, was going to be buried in his own back garden, police have said.
The 36-year-old was discovered by officers in his house at Greenford Road, Greenford, west London on Thursday after neighbours reported concern for the resident.
Upon inspection of the property, detectives found a grave that had been dug but not used.
A spokesman for Scotland Yard described the discovery as "a large hole, big enough for a body, in the garden at the rear of the property".
It is believed that Mr Michniewicz was killed following a fight involving three white males on an evening two or three weeks ago.
Two people, a 20-year-old man and 17-year-old woman, who are understood to be residents of the same house, have been arrested in connection with the death.
Both have been bailed until later this month.
Detective Chief Inspector Noel McHugh of the Homicide and Major Crime Command said: "I am keen to hear from anyone who may have seen anything suspicious at the address or who may have some information.
"I also want to hear from anyone who stayed at or visited the property in the last few weeks."
