OSKALOOSA, Kan. (AP) — Authorities in northeast Kansas say a drug raid led to the seizure of 9,800 marijuana plants from Corps of Engineers property.

KAIR Radio reports the FBI and a Missouri National Guard helicopter took part in Thursday’s raid at a rural Jefferson County home east of the Corps-operated Perry Lake.

The Jefferson County sheriff’s office says the marijuana plants were being grown on Corps land and were being watered from the residential property. Authorities also seized several items of drug paraphernalia from the home.

One man was arrested at the scene on five drug-related counts. He was booked into the Jefferson County jail but posted a $10,000 cash surety bond a short time later.
