An 11-year-old boy has died in an "unexplained" house fire.
The body of Cem Bora was found at an address in Coniston Road, Lancaster, following a blaze which broke out at about 4.50am on Sunday.
Emergency services were called to the property to reports that three people were trapped inside.
An 18-year-old man and a 12-year-old boy had escaped before firefighters arrived.
The 18-year-old was taken to Royal Lancaster Infirmary, with his injuries not thought to be serious.
The 12-year-old is being treated at Liverpool's Alder Hey Hospital, where he is described as "extremely poorly", although police say his condition is thought to be stable.
It is understood that Cem, also of Coniston Road, was sleeping at his friend's house at the time of the fire.
