A call to police from a concerned neighbour who had not seen a man in several days led to the discovery of a body in a Regina house on Friday afternoon.

In a news release, police said they are investigating and were treating the man's death as suspicious.

The man, whose name has not been released, was found in a house in the 1300 block of Grey Street after a neighbour told police he hadn't been seen in several days.

Police said they will be working with the coroner's office on the case.
