A knife-wielding robber demanded cash and cigarettes from a terrified city shop worker on Easter Sunday.
But the thief fled empty-handed from the convenience store on Craigentinny Road, in north-east Edinburgh, after the victim of the attempted robbery refused.
The incident happened at around 6pm.
A man in his twenties approached the assistant at the shop counter and presented a knife.
Police are now urging anyone with information to contact them.
The suspect is described as white, of slim build and around 5 ft 4 inches tall.
He was wearing a dark blue, hooded jacket, dark bottoms tucked into black socks, dark coloured trainers, which had a white logo at the top, and orange or red soles.
He was carrying a black cotton “bag for life” with a white logo on it.
He was last seen running up Loganlea Road.
Detective Constable Kevin Walls said: “We are keen to hear from anyone who may have seen this suspect or who has any information that can help us trace him.
“He may have left empty-handed but he did cause the shop workers fear and alarm when they were simply doing their job.”
Anyone with information is asked to contact officers on 101 or via Crimestoppers on 0800 555 111.
