Police released this mugshot of Mark Revill, 50, ahead of his sentencing this month
Police have released a chilling mugshot of the deranged stalker who waged a terrifying campaign of harassment against Keira Knightley.
Mark Revill left the Oscar-nominated actress fearing for her safety when he flouted a restraining order to send her a series of threatening tweets, in which he described himself as a 'public executioner'.
The 50-year-old suggested he would attack the Hollywood star, her husband - former Klaxons keyboard player James Righton, 33 - and two-year-old daughter Edie at their home.
Using his Twitter handle Mark McCattipuss, Righton also posted images of a naked girl on Twitter.
Police today released a mugshot of Revill ahead of his sentencing at the end of the month.
The tweets came just one month after he received a suspended prison sentence and an indefinite restraining order for meowing through her letterbox and writing her threatening letters.
Ms Knightley beefed up security at her £3.9m north London home after Revill made her too scared to leave the house.
