The PSNI think four men tried to murder an elderly woman found critically injured in her garden in County Tyrone.
They ransacked the 83-year-old's home in the Sydney Street area of Aughnacloy last night.
She was taken to hospital just after 9pm and remains there in a critical condition.
Detectives are also investigating whether it is linked to three other reported burglaries in the area.
Detective Chief Inspector John Caldwell said: "This is a sickening incident in which a vulnerable 83-year-old woman sustained serious injuries. We are investigating the circumstances of the burglary and believe that the lady may have fallen from an upstairs bedroom window while trying to escape while her house was ransacked.
"We take the issue of crime against older people extremely seriously and remain committed to putting those responsible before the courts.
"I am appealing for anyone who has any information about this incident to contact detectives in Dungannon.
"I am particularly keen to speak with anyone who may have seen a black coloured car in the Sydney Street or Moore Street area yesterday evening or last night I would also like to hear from anyone who noticed anything suspicious in Aughnacloy, Ballygawley and Seskinore yesterday."
