HOULTON — An Easton man already in jail on a misdemeanor charge was arrested again Tuesday on charges of trafficking in prison contraband and tampering with a witness.

Scott McEntee, 19, was arrested on a Superior Court warrant after he was indicted last week by the Aroostook County grand jury.

McEntee allegedly smuggled marijuana into the Aroostook County Jail after he was allowed outside on a work detail. He also is accused of threatening a state witness after he was confronted with the contraband allegation.

Both of the new charges are felonies. McEntee could be sentenced to as many as five years in prison for each charge.
