A deputy marshal in a Mississippi town has resigned amid an investigation into a fight after a police chase.

The Commercial Dispatch reports Caledonia aldermen accepted Lance Luckey’s resignation Thursday.

Luckey remains a Columbus police officer. He had worked part-time with the Caledonia marshal’s office for 12 years and was involved in a fight May 11 between officers from Caledonia, Lowndes County and Monroe County Sheriff’s Office and people stopped after a chase.

An affidavit shows 26-year-old Graham Pritchett of Hamilton was charged with aggravated assault on a police officer for allegedly “exhibiting a fixed blade in a deadly manner” to Luckey.

Pritchett was charged with two other counts of assault for allegedly hitting other officers. A Monroe County booking photo shows bruises on Pritchett’s face.
