Police on online child abuse: 'cases never cease to horrify'

More than 500 children have been identified as potential victims of online sexual abuse during a major investigation by Police Scotland.

Police Scotland Assistant Chief Constable Malcolm Graham says the cases never cease to horrify police officers and they show that "the threat is going to change at an increasingly rapid rate".

Malcolm Graham was speaking on The World at One.
