The first organized police department in Vernon was established in 1890 and was known as the Rockville Police Department. At the time of its creation, only four men made up the force. Law enforcement in rural Vernon was the responsibility of local constables.

In 1965, the Rockville Police Department and the Vernon constables consolidated and the Vernon Police Department was established.

Today, the Vernon Police Department consists of 50 officers and detectives committed to providing Vernon residents and those who visit our community the highest level of professional service.
