Appeal after 'laughing gas' stolen from Dumfries hospital
Thousands of pounds worth of nitrous oxide, commonly known as laughing gas, has been stolen from Dumfries and Galloway Royal Infirmary.
A total of 26 cylinders were taken from the hospital's gas compound store between Saturday and Tuesday.
The cylinders are blue, about 5ft 6in (1.68m) tall, hold 9,000 litres of gas and together are worth about £4,000.
Police want to trace two people seen locally in a white van with roof bars between 14:00 and 19:00 on Saturday.
Last year police issued a warning about the increased use of nitrous oxide by young adults in the region.
