The Army has said it is investigating photographs allegedly showing a Scottish soldier dealing drugs.
The Army has warned soldiers that drugs will not be tolerated
The pictures were taken by the News of the World and apparently show a soldier selling ecstasy outside the Glencorse Barracks in Midlothian.
The base is home to the Royal Highland Fusiliers.
Earlier this week it emerged that 20 soldiers from the same battalion face being dismissed from the Army after failing drugs tests.
A spokesperson for the Army said: "We are aware of the story and an internal investigation is going on.
"This type of thing is against everything the armed forces stand for."
She added that if the Royal Highland Fusilier was found to have been doing this he would be dismissed from the Army.
