One year after Louisville Mayor Craig Greenberg changed city policy to allow the Louisville Metro Department of Corrections to honor 48-hour Immigration and Customs Enforcement (ICE) detainer requests, Louisville has moved from exercising local judgment to functioning as a dependable entry point into federal immigration detention and deportation.
The ACLU of Kentucky is calling on Mayor Greenberg to reverse the 48-hour ICE detainer policy and provide a complete public accounting of:
From January 1, 2024, to August 1, 2025, ICE filed 326 detainer requests in Louisville, averaging 17.2 per month.
From August 1, 2025, to March 1, 2026, ICE filed 344 detainer requests, averaging 49.1 per month.
That means the average monthly number of detainer requests was nearly three times as high after Mayor Greenberg changed the ICE policy.
From January 1, 2024, to August 1, 2025, there were 225 ICE detention stints in Louisville.
From August 1, 2025, to March 1, 2026, there were 286 ICE detention stints.
That means the average monthly number of ICE detention stints increased by approximately 245% after Mayor Greenberg changed the ICE policy.
From January 1, 2024, to August 1, 2025, there were 388 non-custodial ICE arrests in the Louisville area.
From August 1, 2025, to March 1, 2026, there were 231 non-custodial ICE arrests.
The average number of monthly non-custodial ICE arrests was approximately 62% higher after Mayor Greenberg changed the ICE policy.
Federal records show that in the months after Mayor Greenberg changed the policy, 157 people who received detainer holds in Louisville were later removed from the United States by ICE.
This reporting is based on data the Deportation Data Project obtained from ICE via public record request. Detainer requests refer to requests by ICE to hold someone in jail for 48 hours beyond their ordinary release time to allow ICE the chance to arrest them.
Detention stints refer to the time that an individual spends in a facility during their time in ICE custody. A person can serve detention stints at multiple facilities during the period of a single incarceration. The arrest data includes all arrests conducted by ICE, whether or not ICE decided to detain the individual arrested.
