Nitrous oxide gas cylinders stolen from Dr Gray's Hospital in Elgin
Police have appealed for information following the theft of medical gas cylinders from an Elgin hospital.
It is thought the nitrous oxide cylinders were stolen from Dr Gray's Hospital at about 22:20 on Friday.
Police are particularly keen to speak to two men aged about 25 with local accents, and a woman described as being about 18-years-old.
They were seen driving away from Pluscarden Road in a white car with the boot open.
One of the men was said to be wearing a black jacket and jeans, and the other a blue jacket and jeans. The woman was described as having long black hair.
PC Brian Donaldson, who is investigating the theft, said: "Nitrous oxide, or N2O, is commonly known as laughing gas and has analgesic properties when used medically.
"However, worryingly, it has been known to be used illegally as a recreational drug and can be used by car enthusiasts as a fuel additive.
"Nitrous oxide can be a dangerous substance if it is misused or consumed without medical supervision. Also, any attempt to interfere with the pressurised cylinders may result in serious injury if they are not handled correctly."
