Authorities discovered four pounds of marijuana after firefighters put out a blaze in an East Providence building.
The Providence Journal reports that the fire broke out around 11 a.m. Tuesday in a three-story building that houses a liquor store and apartments.
Police Lt. William Nebus says firefighters discovered growing lights used for marijuana and called police.
Police say while some residents of the building had medical marijuana cards, they are only allowed to have up to 12 plants and 2.5 ounces each.
A 22-year-old woman was arrested. Her name was not immediately released.
