(AP) — A northeast Kansas couple has sued authorities after a SWAT-style raid of their home came up empty-handed for marijuana.

Adlynn and Robert Harte of Leawood filed suit in federal court Tuesday against the Johnson County board of commissioners, Sheriff Frank Denning and several deputies for the April 2012 raid.

The sheriff’s office referred questions to its attorney, who did not immediately return a call.

The lawsuit contends the raid was prompted by the Hartes’ purchase a few months earlier of hydroponic growing equipment for an indoor vegetable garden.

Authorities obtained a search warrant after misidentifying wet tea leaves found in their garbage.

The Hartes say in an emailed statement they hope the lawsuit prompts an examination of what they called reckless law enforcement practices.
