Detectives in Inverness are appealing for witnesses after a robbery at a shop in the city.
The incident happened after an attempted robbery at the same premises the previous day.
An unidentified man entered Laidlaws on Bruce Gardens in the Dalneigh area of the city shortly before 10pm on Saturday, 31 July and threatened the staff member with a knife.
The shop worker managed to repel the man who then fled.
The man is described being around 6ft or above in height, and of slim to medium build.
He was wearing a blue and black hooded jacket with a white logo on the rear and dark bottoms.
He was also wearing blue latex style gloves and a face covering.
At the same premises around 11.45am on Sunday, 1 August, a man again entered the shop and threatened a staff member with a knife and a wooden stick.
He then stole a sum of cash from the till, estimated to worth between £100 to £200 before leaving the shop.
On this occasion the man was wearing a black hooded top with a large white Adidas logo on the front, blue jeans and dark trainers.
Detective Sergeant Joanna Macleod said:
“Both of these incidents were frightening ordeals for the staff members involved.
“These are unusual incidents for Inverness and we are carrying out extensive enquiries to identify the man responsible.
“While we are keeping an open mind, we are treating the incidents as linked.
“I would urge anyone who saw a man matching these descriptions on either Saturday night or Sunday morning in the Dalneigh area to come forward.
“I would also be keen to speak to anyone who may have private CCTV or dashcam footage from the area.
“Anyone who can help is asked to call 101, quoting incident 1639 of 1 August, or call Crimestoppers anonymously on 0800 555 111.”
