Very few details have been released, but Benton County Sheriff's Deputies say they raided a farm at 12201 North Griffin Road near Prosser Thursday.

What prompted them to get a search warrant was not revealed, (probably drone surveillance footage) but upon arrival and searching, they found over 257 large marijuana plants growing illegally among what appears to be rows of hops.

NO word if any arrests or other details, Deputies say that's due to ongoing investigation.
