DALLAS (AP) – Prosecutors say 18 people have been arrested in the investigation of a North Texas marijuana trafficking ring.

Authorities say a federal indictment unsealed Thursday in Dallas includes charges of conspiracy to possess with intent to distribute marijuana.

Officers seized marijuana, cocaine, vehicles and several guns as part of the investigation. Three of the suspects also face money laundering-related counts.

The defendants are from Dallas, Irving, Cedar Hill and Midlothian.
