Irish police say a dead man's badly decomposed remains have been found in an occupied Dublin house and may have lain there, undisturbed, for four years.

Thursday's macabre discovery in the inner-city district of Phibsborough follows renovations in the property.

Police say the house's residents were illegal squatters and drug users.

They say the previous tenant may have died during a fire at the property in 2009, but his body was not seen by firefighters and eventually obscured by a broken piece of furniture.

A pathologist says the man appears to have died from natural causes, and DNA and dental records may be needed to identify him.
