The Lafayette Police Department Civil Disturbance Unit (CDU) was formed in 1999. A civil disturbance at Purdue University following the victory of the women's basketball team in the NCAA tournament brought to light the necessity for a more modern, well equipped team that could deal with similar situations in Lafayette and surrounding jurisdictions.
The objective of the CDU is to function as a cohesive unit and adapt to constantly evolving situations within disturbances by using minimal or no force to resolve the issue. CDU trains and is prepared to handle many situation including, but not limited to:
Correctional institution issues
Passive/active resistor protests
Sporting event celebrations
The CDU can also be utilized for missing person searches, perimeter security for SWAT team operations, and assistance to EMS and Lafayette Fire for Hazardous Material incidents. CDU members also help make up the IDHS District 4 Homeland Security Task Force.
