Two police officers were assigned to an event featuring a controversial speaker in Douglas last month.
Katie Hopkins performed at the Manx Legion on Market Hill in Douglas on September 13, and a Freedom of Information Request asked police for more details.
The Constabulary said two officers were assigned duties to cover the event, and no complaints were received.
However, questions about arrests and people who allegedly shouted abuse at Katie Hopkins and harassed attendees couldn't be answered because the information could be used as part of a criminal investigation.
