On June 1, 1978 the Hinckley Police Department hired its first full time officer. Leonard P. Keller was hired as a Police Chief to organize and establish a full time department.
A levy was passed in November of 1978 to establish funds for additional full time personnel. In January of 1979 4 additional personnel were added to the department.
Leonard Keller left the department in 1982 and Melvin Wiley was appointed Chief of Police. Chief Wiley disappeared in July of 1985 and was replaced by the recently retired Chief, David Yates.
Over the years the department has grown along with the Township. Additional personnel were hired and the department is now comprised of 10 full time police officers, 2 part time police officers and 2 civilian dispatchers.
