Investigators are reviewing their missing persons' file after a man's body was pulled from the Ottawa River near the prime minister's home Friday morning.

A fisherman who saw the body floating in the river near 24 Sussex Dr. reported the discovery at about 7 a.m.

Police say the body had already started decomposing, indicating it had been in the water for a long time.

Police say it may take a few days to determine the man's identity and cause of death.
