Of the seven adults inside the home during the raid, six were arrested on various drug charges. A teenager in the home was placed in protective custody.
Early Tuesday morning police executed a search warrant at a home in the 3900 block of North Massachusetts Avenue, according to Lt. Robert King with the Portland Police Bureau.
Officers said they found nearly 20 grams of marijuana, more than 10 grams of heroin, a sawed-off shotgun, thousands of dollars in cash and the materials for a methamphetamine lab inside the home.
"The neighborhood response team began this investigation over a year ago because of numerous neighborhood complaints," King said. "At one point a neighbor gave officers an 8-inch by 10-inch flier found in the neighborhood that said 'Heroin for sale' and gave the address and the names of the dealers."
