A woman has been arrested after a fire broke out at a home in a village near Acle.
Fire crews were called to a property in Sutton Crescent in Freethorpe at 2.50am today.
Firefighters wore breathing apparatus and used main jets and hose reel jets to extinguish the blaze.
The ambulance service was alerted but stood down once it was certain there were no patients.
A Norfolk Constabulary spokeswoman has since confirmed the incident is being treated as arson.
"Police were called to assist the Norfolk Fire and Rescue Service at 2.55am this morning following a report of a fire at a property on Sutton Cresent in Freethorpe," she said.
"The fire is being treated as arson and a woman aged in her 30s has been arrested in connection with the incident.
"She was taken to Wymondham Police Investigation Centre, where she currently remains in custody."
