Police were called at about 7.40pm on Tuesday (06/03) about a disturbance at a Fenny Stratford Town Council meeting at the Queensway Methodist Church in Bletchley.
Thames Valley Police are appealing for witnesses to the event.
It was reported that a member of the public had barged into the meeting and there was a verbal altercation.
The meeting was abandoned.
The Milton Keynes Neighbourhood Policing Team is carrying out an investigation into an alleged offence under the Public Meeting Act in relation to the disruption of the proceedings.
The team is also investigating a report of a racially aggravated public order offence, following an allegation that racist comments were made outside the building.
Inspector Michael Morland, of the Milton Keynes Neighbourhood Policing Team, said: “We will not tolerate hate crime within our communities. Reporting any information to us means we can take positive steps and help to prevent it from happening to someone else.
“If anyone witnessed the incidents on Tuesday evening and has not yet spoken to officers, please call the Thames Valley Police 24-hour inquiry centre on 101, quoting reference 43180069387.”
