A 41-year-old man has been jailed for three years for the harassment of RTÉ newsreader and journalist Sharon Ní Bheoláin.

Conor O'Hora, from Heather Walk in Portmarnock in Dublin, pleaded guilty to the charge and to three counts of possessing pornographic material related to children.

The court heard O'Hora harassed Ms Ní Bheoláin between March 2013 and January 2014 by posting pictures on a website of her face superimposed onto pornographic images.

When gardaí searched his home and seized a computer and a mobile phone following a complaint by Ms Ní Bheoláin, they found material that led to the child pornography charges.

Judge Martin Nolan said the harassment of Ms Ní Bheoláin was insidious and the possession of child pornography was always serious.

He said it was an aggravating factor that the majority of images related to the young child of someone O'Hora knew.

These pictures had been taken from Facebook and doctored to turn them into extremely explicit images.

Judge Nolan said images of Ms Ní Bheoláin on the internet would be "out there forever" and may have been downloaded by other parties.

He said the appropriate sentence was four-and-a-half years but he suspended the final 18 months on condition that O'Hora be of good behaviour and undertake not to contact Ms Ní Bheoláin directly or indirectly.
