ALBUQUERQUE, N.M. (AP) - Authorities say they have arrested a New Mexico teenager accused of using social media to peddle fentanyl, assault weapons and other firearms.

  

Bernalillo District Attorney Raul Torrez on Wednesday announced the 17-year-old's arrest. Authorities said it came after a multi-agency investigation that involved the FBI and state police.

  

The teen is expected to make an appearance Thursday in Children's Court on drug-related charges and unlawful possession of a firearm. The Associated Press is not naming the teen because of his age.

  

An FBI search warrant showed the teen was arrested early Tuesday morning at a house in southwest Albuquerque.

  

FBI and state police agents' list of items seized included 60 tablets they suspected to be the powerful opioid fentanyl and a loaded AR-15 pistol with a 30-round magazine.
