The father of teenager, Hannah Smith, who committed suicide after she was allegedly bullied on a social media website, has called for laws to be changed.

David Smith told the BBC his daughter was being abused by somebody online and it needed to be stopped.

He said he would prefer the website ask.fm, which Hannah used, "to disappear" after the grief he had been caused.
