Detectives hunting a masked man who robbed a petrol station in Cardiff armed with an axe have released CCTV images of the incident.
The robbery at the Co-op garage on Llantrisant Road in Llandaff happened at around 0040 BST on Monday.
A man wearing a Halloween mask and carrying an axe threatened a female member of staff before demanding cash.
Police want to trace a man who bought the same type of mask from the garage two weeks ago.
A spokesperson for The Co-operative said: "The members of staff were unharmed but badly shaken."
Anyone with information is asked to contact Fairwater CID on 02920 527248 or Crimestoppers on 0800 555111.
