A man threatened to bomb an MP’s house and “show her what it's like to murder innocents” after she voted in favour of Syria air strikes.
Craig Wallace, 23, launched a tirade of abuse on Facebook aimed at Tory MP Charlotte Leslie, who represents Bristol North West, the Press Association reported.
In one post he said: “I'm going to smash her windows then drop a bomb on her house while she's tucked up in bed. You dirty fucking pig-shagging slut.
In a second post, published on December 3, the day after the Commons vote on the issue of UK military intervention in Syria, he said: “I'm going to find her and show her what it's like to murder innocents. You dirty pig-fucking whore.”
Wallace, who calls himself Muhammad Mujahid Islam on Facebook, has a string of convictions for violent offences including possession of a knife.
He converted to Islam while in prison serving a sentence of almost five years for attempted robbery.
Three weeks after he was released he posted the messages on a thread of comments on the UK Truth Movement Facebook page.
Wallace, of Willesden Green, north London, pleaded guilty to sending threatening communications at Hendon Magistrates' Court. He was remanded in custody and will be sentenced on December 30.
The comments came to light when Leslie’s father saw them online and reported them to police.
Wallace claimed he was “venting his anger” and had not had any sleep because he had been “protesting for two or three days”.
District Judge Mark Jabbitt said: "What's absolutely clear is that your language and expressions about this MP Ms Leslie, who you have no knowledge of, went beyond any sort of legitimate comment or protest on an extremely serious issue.
"What you did was personalised it and used really the most vile, insulting and threatening language imaginable on a forum."
He ordered a full risk assessment report on Wallace and expressed concern that he was not being formally supervised after his release from prison.
Abu Sayeed, defending, said Wallace has mental health issues and had not been taking his anti-psychotic medication.
"He has co-operated fully with the police and expressed remorse and regret," he added.
"He made the comments to vent his anger.
"Mr Wallace is a Muslim convert, he converted while serving his last sentence. He feels very passionately about the bombing in Syria and the vote recently taken in Parliament.
"He had been out with other protesters and was protesting for two or three days and not had much sleep and hadn't taken his medication."
Wallace has never met Leslie and thought the page was a "closed group", Mr Sayeed said.
A number of MPs were sent threatening messages and abuse after voting in favour of intervention in Syria.
Labour MP Neil Coyle was sent a tweet containing knife emojis, while Simon Danczuk and Stella Creasy also said that they received abusive messages.
