WHITBY, Ont. -- Durham regional police say more tests are needed after an autopsy failed to determine how a 30-year-old man died after a fight at a Whitby home.

Police say they have new information about what happened and are now calling the man's death suspicious rather than a homicide.

The man was found in the basement of the home Saturday morning and died after being taken to hospital.

Police have not made any arrests and say they are not looking for suspects.

The man's name has not been released.

Police want to hear from anyone with information about he case.
