Police on Wednesday arrested an 83-year-old man in Rome accused of knifing his carer in the chest in a fit of rage after she allegedly left a window open.
The 46-year-old woman was taken to hospital after the late-night attack at an apartment in Rome's eastern Tor Bella Monaca district, but doctors said her life was not in danger.
The pensioner is being held in Rome's Regina Coeli jail pending charges.
