A Nottinghamshire man is fighting for his life after he was stabbed by an intruder who broke into his house.
The victim, 65, was knifed in the stomach and chest during the attack at his home in the village of Halam, just after 4am on Thursday.
The perpetrator is believed to have smashed his way into the back of the house, Nottinghamshire Police said.
The 65-year-old went to investigate the sound of breaking glass before being stabbed by the suspect who then ran off, the force said.
The victim suffered serious injuries and was taken to the Queen's Medical Centre for surgery, where he remains in a serious condition.
Detective Inspector Gayle Hart, leading the investigation, said: "This is a horrific incident which has left a man fighting for his life and his family who were upstairs at the time are extremely shocked and upset by the ordeal.
"The victim is in the intensive care unit and is currently in a serious but stable condition.
"Detectives are working hard to establish the circumstances and progress the investigation as quickly as possible.
"We're continuing to make enquiries and are determined to bring those responsible to justice, and we would reassure the public that reports such as this are taken extremely seriously."
