Staffordshire Police have confirmed that they are investigating a complaint from Port Vale chairman Norman Smurthwaite.
Smurthwaite has reported a number of abusive Twitter posts to the Police.
The Vale owner told BBC Radio Stoke: “I have had abuse, some very inappropriate abuse, really crossing the line, I have reported it to the police.”
Staffordshire Police told The Sentinel: ” We are aware of Mr Smurthwaite’s complaints regarding comments posted on Twitter. Our investigation is in its early stages so it is not yet appropriate for us to be requesting any data from Twitter, with whom we have a very good working relationship.”
