A convicted sex offender who hid behind the online nickname ‘Dangerous Dave’ has been caught trading sickening images of child abuse.
More than four hours of video footage showing children from infancy to age 15 being brutalised were recovered from a memory stick and computer owned by paedophile David Greig.
A large number were assessed by investigators as being at the very highest levels of classification.
Police officers found that Greig, 34, had been distributing large numbers of the indecent images over the internet.
He had also accepted indecent images from other perverts, whom he contacted through Skype.
Greig was already well known to the authorities, having served a three-year sentence in a young offenders’ institution following his conviction at Perth Sheriff Court in 1998 in connection with charges of lewd and libidinous behaviour.
He was still on the sex offenders register but his new offences came to light only by chance, after police officers spoke to him on October 11 last year on an entirely unconnected matter.
They discovered a USB stick in his pocket and he admitted that it contained indecent videos and images of children.
A search of his home in Allan Terrace, Perth, saw officers discover further indecent material on the computer found in his bedroom.
Greig admitted possessing indecent images of children over a 12-month period, between October 2012 and October 2013.
He also admitted distributing or showing indecent photographs of children between May 25 and September 3 last year.
Both offences took place while he was subject to sexual offences legislation.
“In summary, the officers discovered 22 still images on the USB 19 at level one and three at level two,” said depute fiscal Carol Whyte.
“There were 81 videos, with a total running time of around four hours, with three classified at level one, 20 at level two, five at level three and 53 at level four.”
Level four includes some of the worst images of abuse.
Greig, a prisoner at Barlinnie, will be sentenced on March 6.
