More CCTV images have been released of the person who took around ?25-thousand pounds worth of jewellery from a shop in Douglas.
The theft from RHS Jewellers on Prospect Hill took place on Friday afternoon at about 4pm.
The shop owner was threatened with a claw hammer, before the thief made off with a number of items from the window display.
He left on a stolen motorcycle, and was wearing a distinctive cycle helmet.
It's hoped the pictures on police social media pages will help trigger some memories.
Detective Sergeant Brian Shimmin.
