AMESBURY (CBS) - An Amesbury man is facing drug charges after officers found 25 marijuana plants growing in a secret room behind a closet in his home.

Michael Makiej was arrested over the weekend and charged with drug possession with intent to distribute.

Police say a tip from California authorities sent them to Makiej's home.

They were told that a package containing two pounds of marijuana was being shipped to Makiej's address.

Officers got a warrant to seize the marijuana and to search Makiej's home.

They found some small marijuana plants and a significant amount of growing materials in Makiej's room.

Believing there was more marijuana in the house, officers continued their search and found a secret room behind a closet.

That secret room contained about 25 plants, large lights, temperatures gauges and a venting system.

Amesbury police called it one of the most elaborate marijuana-growing systems they've ever come across.
