BANGOR — Police say a 3-month-old baby was strapped into a children’s car seat in the back of a vehicle when they turned up an ounce of heroin and 229 oxycodone pills during a traffic stop in Bangor.

Bangor police and Maine Drug Enforcement Agency agents seized $21,000 worth of illicit drugs when they stopped a Lincoln Navigator on Friday. Four suspects who allegedly sold the drugs from Bangor motel rooms are being held in the Penobscot County Jail on drug trafficking charges.

Officials tell the Bangor Daily News that the Department of Health and Human Services was called in after the baby was discovered in the vehicle.
