Tens of thousands of pounds have been stolen in a cash-in-transit robbery.
The incident happened at around 10.15am on Tuesday at the Bank of Scotland branch on Smithycroft Road in Riddrie, Glasgow.
A G4S security guard was outside the bank when he was approached by a man wearing dark clothing and a balaclava.
The 52-year-old was threatened by the man with a knife before robbing him of a money cassette which contained a mid-five-figure sum of money.
He got into the passenger seat of a dark-coloured Audi A4 which headed south towards Riddrie Knowes before the vehicle was found burnt out nearby in Riddrie Crescent a short time later.
Detective Sergeant Neil Guy said: “This was a very traumatic experience for the security guard who was just carrying out his daily job. Luckily he was not physically injured but nevertheless it has left him very shaken up.
“Enquiries are at an early stage and we are appealing for any information that will help us trace the men responsible for this robbery as soon as possible.
“In particular we would ask any motorists with dashcams who were in the area around the time of the incident to check their footage in case they have captured anything which could be of significance to our enquiries.
“At this time we are not linking this robbery to similar robberies in the east end of Glasgow recently, however we cannot rule anything out at this early stage.”
Anyone with information is asked to contact 101 quoting reference number 0916 of 12 March 2019, or call Crimestoppers on 0800 555 111.
