A soldier was caught with indecent images of children on his mobile phone at an army base and threatened to kill a police officer.

Fraser Waddell, 21, of Macmillan Street, Larkhall, South Lanarkshire, served as a private in the Royal Scots Dragoon Guards.

He was arrested after police swooped on his room at the Leuchars Station in north east Fife.

Dundee Sheriff Court was told Waddell's mobile phone contained 21 indecent images of children in the cache of the Google Chrome browser.

The court was also told some images were at the top end of the scale used to measure such pictures.

A month after the raid Waddell phoned Police Scotland Tayside Division's Dundee HQ threatening to seek out a specific officer and to kill him and others.

Fiscal depute Sue Ruta told the court: "He was asked to provide the PIN for his phone but said it wasn't his. It was found to belong to his ex-partner who said she had given it to him.

"Upon examination it was found to contain 21 indecent images of children in the cache of the Google Chrome browser. Search terms indicated he had actively sought them out."

Waddell pleaded guilty on indictment to a charge of taking or making indecent images of children on May 24 last year.

He was on two separate bail orders at the time. His not guilty plea to possessing extreme porn images was accepted by prosecutors.

Sheriff George Way deferred sentence until November 9 for social work background reports and released Waddell on bail meantime.
