A mother and her young son have died in a suspicious fire at their home in Cornwall, police have said.
Patricia Philpotts, 44, and son Ben, 10, were found at the house in Trevarrian, Newquay, Cornwall, early on Monday morning.
The mother was confirmed dead at the scene, while Ben was pulled from the blaze and died later in hospital.
Devon and Cornwall Police first described his condition as "serious" after being called to the scene by firefighters at 6am.
The force confirmed that he had died later at Treliske Hospital in Truro.
A male suspect, aged 47, is due to be questioned once his injuries improve.
He is being treated at Bristol's Frenchay Hospital for wounds thought to have been sustained in the blaze.
The scene has been sealed for a full forensic examination. The force said it had begun a "major investigation" into the incident at the property, named Sundown.Reuse content
