A man has pleaded guilty to stalking actress Keira Knightley and bombarding her with cat-themed messages between August and October this year.

Mark Revill from Hackney admitted to making miaowing noises through the Hollywood star's letterbox at her London home and sending her music about cats on a USB memory stick.

Prosecutor Simma Khan told Highbury Corner Magistrates that Mr Revill's behaviour was "bizarre".

The stalker admitted to police that he was in love with the actress.
