Police Scotland is seeking witnesses following the report of an assault and robbery in Irongray Road last night between 8 pm and 9.30 pm.
The thugs targeted a 77-year-old woman and her husband, 78.
The husband was rushed to Dumfries and Galloway Royal Infirmary with significant injuries following the attack where he remains at this time in a stable condition.
At this stage it is thought that two men and one woman were involved, and jewellery and cash with a value of over £60,000 were taken in the raid.
Detective Inspector Dean Little said: “At this time police officers remain at the scene and we are carrying out door to door enquiries in the immediate area and gathering in CCTV. We are particularly keen to hear about any sightings of the following described two men and a woman.”
The first man is described as being around 6ft 1 tall, average build wearing dark clothing.
The second man is described as 5ft 9 tall, slim build and dark clothing. Both men spoke with northern English accents.
The woman is described as around 5 foot 2 tall, larger build, pale white skin, about 40 years old with dark brown shoulder length hair and spoke with a local accent.

“We are asking anyone who lives or was in the area of Irongray Road, or the surrounding area to get in touch with us if they saw any of the people described.
“Likewise we would be keen to hear about any strange vehicles which might have been seen entering or leaving, or even parked up in the area of Irongray Road or surrounding streets on Sunday night.
