Liam Corr, 21, of Oliver Plunkett Road, Dun Laoghaire, Co Dublin had previously been banned by his mother from using a smartphone after she caught him using it to access explicit material.

When gardai subsequently analysed the device they discovered 28 video files.

Thirteen showed underage girls engaged in sexual activity with both adults and other children, 14 depicted similarly-aged children engaging in more explicit sexual activity and one showed a girl engaged in bestiality.
