The Maine Drug Enforcement Agency on Friday arrested a local man for selling heroin in the Sanford area, police said in a news release on Monday.

Shane Eisener, 40, of Sanford was charged with aggravated trafficking in schedule W drugs.

Eisener and other suspects routinely traveled to Massachusetts to purchase heroin that was later sold in greater Sanford, Maine Department of Public Safety spokesman Stephen McCausland said in the release.

Late Friday night, drug agents and state and local police stopped a car on Sanford Road in Wells that Eisener was a passenger in. Police said the people in the car were returning from Lawrence, Massachusetts with heroin and cocaine.

Police seized 42 grams of a heroin/fentanyl mix and 15 grams of cocaine HCL from Eisener, the release said. The approximate street value of the drugs that were confiscated was $7,800.

Eisener was transported to the York County Jail. No bail has been set for Eisener because he was already out on bail for an unrelated charge. He was expected to make hos first court appearance on Monday.

The driver of the vehicle was released pending a review of possible charges by the State’s Attorney General’s Office.

Police said the investigation is ongoing and additional arrests are expected.
