A man from Downham has been warned he faces arrest if he continues to post abusive comments about a former MP via social media.
Police say the 24-year-old, who has not been named, has been given a harassment warning in relation to remarks made about Jackie Doyle-Price on Facebook.
Miss Doyle-Price, who is defending the Thurrock constituency for the Conservatives at the forthcoming general election, was abused on Facebook after she supported a police campaign against car cruisers in January.
Investigating officer PC Paul Armstrong, of Essex police, said the warning was a “first instance” one and the man could be arrested if he persists.
He said: “Hopefully this will send out a clear message that ‘trolling’ people on social media is not acceptable and we will take action against those who do.”
Miss Doyle-Price, who is understood to have complained about the comments last month, has previously branded drivers who parade their customised vehicles were a danger to road users and a “noise nuisance.”
She also described people who post abusive messages anonymously as “sad and inadequate”.
She said: “I am grateful to the police for taking this action.”
