David Porter downloaded indecent images of children
An IT worker from West Dunbartonshire has admitted downloading indecent images of children.
David Porter, 33, from Alexandria, was caught at his former home in Glasgow after police received a tip-off.
Officers later found 71 moving images on his computer ranging from level one to level five - the most extreme.
Porter pleaded guilty to downloading indecent images of children between October 2009 and April 2012. At Glasgow Sheriff Court, sentence was deferred.
Procurator fiscal depute Adam Roberts told the court: "A warrant was sought and granted by the sheriff at Glasgow to search the home address of the accused, on the basis of intelligence information implicating the user of a computer located at that address in the downloading of indecent images of children."
The court was told officers went to his tenement home in Glasgow's Dennistoun area where he lived at the time with his partner.
Police officers told the couple why they were there and about the warrant they had.
Mr Roberts said a search was carried out and a laptop and external hard drive were found and the couple were taken to London Road police office.
He said: "The accused was thereafter interviewed in the presence of his solicitor. He made full admissions and stated he would like help.
"The accused admitted that he had downloaded indecent images of children.
"He said that he was not sure how frequently he had done this, or how long he had been doing so far, but accepted that he had been downloading the images 'since before Christmas 2011'."
The court was also told that all of the video files were recovered from the external drive and had been deleted.
They were not accessible to the ordinary computer user and recovered only by means of specialist forensic examination techniques.
