COMMACK - Officials announced the arrest of a Kings Park man for the cultivation of nearly 100 marijuana plants in a secluded water recharge basin located in Commack.

Police say Mark Kern, 54, has been charged with criminal possession of marijuana, criminal trespass and resisting arrest. According to police, the plants were seized near Motor Parkway and Red Leaf Lane.

The four-month probe, deemed “Operation Green Thumb,” started after two Smithtown highway workers located the plants in May. Shortly after, authorities began actively surveying the location.

Police say at least two suspects were recorded tending to the farm over that period of time. The plants were not harvested yet, so no marijuana was sold, according to police.

According to officials, the weight and street value of the plants, measured to be 7-10 feet, have yet to be determined.

Detectives say the involvement of other individuals will be determined by a follow-up investigation and that additional arrests may be made.
