Three masked men dressed in camouflage clothing and armed with air rifles robbed a group of teenage boys as they camped near Clatto reservoir.
Dundee Sheriff Court heard Kieran McIntyre, 20, Liam Scott, 19, and Adam Parkin, 19, shone torches into the boys’ tent and demanded they get out.
They then made the boys sit on rocks while they pointed air rifles at them and shone torches in their faces.
McIntyre, Scott and Parkin then robbed the younger boys.
Fiscal depute Eilidh Robertson told the court the incident happened on March 7 last year.
She said the four youths had pitched a tent and sat at a camp fire before going to bed around 11pm, leaving their bags outside.
But around midnight they were wakened by noises suggesting a group of people were rummaging through their bags outside.
The fiscal said: “One youth was then aware of the tent being touched in the area where his head was and he moved his head before the same area was kicked.
A torch was then shone into the tent and Scott said words similar to: ‘Are you getting up then?’ and: ‘Get out of the tent.’”
Three of the boys exited but one stayed inside, sleeping.
Parkin held a torch in their faces and pointed a rifle towards them and said: “Run and you will get shot.”
McIntyre, Scott and Parkin were all dressed in camouflage or military style clothing with faces masked and only eyes visible.
Parkin then demanded the fourth boy get out of the tent and said: “I’m giving you 30 seconds to get out here or I’ll blow your head off.” The boys handed over £5, mobile phones and cigarettes.
One boy said his phone was in the tent and Parkin pressed the barrel of the gun into the back of his head and told him to get it.
Parkin, Scott and McIntyre then told the boys not to leave before sunrise as they were watching and they would be shot if they tried it. The boys waited until morning before leaving.
McIntyre, of Clepington Street, Scott, of Eden Street, and Parkin, of St Dennis Terrace, all admitted one charge of robbing four males under the age of 16, between March 7 and 8, at Baldragon Wood.
Scott and Parkin further admitted a second charge of having an air rifle on the same date and location.
Sentence was deferred until November 24 for reports.
