A nun has been treated for a sprained wrist and a bump to her head following a robbery at a convent in Kent.
She was assaulted after hearing the noise of breaking glass in an office at St Bart's Convent, in Swanley.
When the 76-year-old went to find out what had happened, she discovered a man taking a laptop computer and grabbed him by the arm.
The robber pushed her away causing her to hit her head and fall, before he fled with the computer and a handbag.
Police said it was believed a second person was outside the window at the time.
The laptop did not hold confidential information but did have work needed to teach students with special needs.
The man who took the computer and assaulted the nun was described as white, aged 18 to 22 years old, and about 5ft 5in tall.
He was wearing a grey hooded top and black trousers.
Acting Det Sgt Ben Turner said: "This incident could so easily have become something much worse.
"She [the victim] was very brave and felt it was her duty to try to stop the offender."
