Detectives are treating a house fire near Carnforth as a suspected arson attack, it has emerged.
Firefighters were called to a property in Pear Tree Park at Holme at 2.23am on Monday.
Police said a 49-year-old man was inside his home when, at around 2am, the fire started.
But he was alerted to the fire when a smoke alarm was activated.
He then managed to escape the property and was not injured.
Three fire crews - one each from Milnthorpe, Kirkby Lonsdale and Arnside - were sent to tackle the blaze.
Cumbria Fire and Rescue Service said the fire had started in the hallway of the two-storey terraced home.
Crews donned breathing apparatus before using two hose reel jets to fight the flames.
In a statement, Cumbria Police made a public appeal to anyone with information to come forward.
“Police would like to reassure the public that such events are very rare and to take the opportunity to remind people to check their smoke alarms on a regular basis,” it read.
“Police are appealing for any witnesses who may have seen any suspicious movements, persons or vehicles between 2am and 3am in the area at the time to contact Kendal CID on 101 or Crimestoppers on 0800 555 111.”
A spokeswoman for North West Ambulance Service said the man was taken to the Royal Lancaster Infirmary to be checked over.
