The Village of Maineville Police Department came into being in the 1950's.  After years of operating with a Village Marshall, which was actually a Deputy Sheriff on special duty, Maineville appointed its first Police Chief.  Glenn Frazier was chosen and led the department. 

In September of 1970, The Village took the next step with the appointment of Police Chief Joe Lane. 

In 1973, a dispute between Hamilton Township and the Warren County Sheriff resulted in the loss of County coverage.  In an emergency meeting of the Maineville Council, an agreement was made to have the Maineville Logo affixed to the township cruiser and Maineville began providing police services to the residents of Hamilton Township.  Soon thereafter, the County resumed normal patrols and the Village returned to patrolling within the Village only. In 1997, Chief Lane was promoted to Full-Time Status by the former Mayor John Michael.

In 2001, The Village enacted an Earned Income Tax Ordinance of 1% which now funds all Village departments except the Street Department.  We continued to contract on a year by year basis with the Hamilton Township Police Department.  In August of 2004, while still under contract with the Township, the Village sat aside $50,000 to begin building the new department. In January 2005, the Village appointed Andrew Roosa as Chief of the new department. The Warren County Sheriff's Office donated a cruiser which was painted free of charge by Carstar of  Blue Ash. By March of 2005, the Village began providing routine police patrols once again, with the Sheriff's Office providing additional support.

Sgt. John Reynolds was appointed Chief of Police in August of 2006. Since Chief Reynolds became Chief an additional vehicle, a 2008 Ford, has been added to the police fleet. The Police department also supports a bike patrol program.

It is the goal of the Village police department to continue to expand our services to provide the most comprehensive police coverage and community based programs available.

Maineville Police Department recently worked with the residents of Salt Run subdivision to create a Neighborhood Watch program and participates in the Project Child safe program providing free gun locks to residents.
