No. But I suspect his local MP will ask the Police to investigate. The officer who asked the police to pop round will probably be nagged for being naive. There may be a weak apology and it'll blow over. The damage I suspect will be for the politician who attempted to misuse a complaint about online bullying as political intimidation. UKIP won't be affected because they're a protest party, most people voting for them don't care about their tactics they see them as a single-issue party.
Edit: fat fingers and predictive text!
