Police are appealing for information following a housebreaking in Cupar, which took place around 11.40am on Thursday in Station Road.
A man forced entry to a ground floor flat and stole jewellery boxes containing a number of items, some of which were engraved.
A 61-year-old resident returned home and challenged the intruder, who then threatened him before making off.
The suspect is described as white, aged 20-30 years, 5ft 8-9inches tall, of slim build with short brown hair and glasses.
He was wearing a dark blue zipped hoodie, light grey tracksuit trousers and white trainers.
