Police investigate Lord Janner abuse allegations in Scotland

Police Scotland are investigating allegations of child abuse by Lord Janner, said to have taken place in Scotland in the 1970s.

In May, the Crown Prosecution Service in England and Wales said it would review its decision not to charge Lord Janner over allegations of historic child sex abuse.

He had been deemed unfit to stand trial because of dementia. Lord Janner has always denied any wrongdoing.

BBC Scotland home affairs correspondent Reevel Alderson reports on the sequence of events.
