An anonymous eTip program struck again in the battle against underage drinking when Bath police charged four minors Monday with alcohol- and drug-related offenses.

Officers received a report from the eTip program at about 9 p.m. Monday that there was an underage drinking party at 301 Oak Grove Ave. Officers reportedly found minors drinking and smoking marijuana, according to Bath Lt. Stan Cielinski.

A 17-year-old male was hosting the party while his mother was out of town. He was summoned on a charge of furnishing a place for minors to consume alcohol and possession of a usable amount of marijuana. The 17-year-old was on probation already from a prior conviction.

Other summonses were issued to Amber Moore, 19, of West Bath on a charge of possession of alcohol by a minor; Matthew Lathan, 19, of Bath on charges of possession of alcohol by a minor and sale and use of drug paraphernalia; and a 15-year-old Brunswick male was charged with possession of alcohol and possession of a usable amount of marijuana. The juveniles were released to the custody of their parents.

Monday’s arrests are the latest in a string of charges involving underage drinking over the last several months as police continue to focus on the problem in the Mid-coast area.

The eTip program is an anonymous tip line that allows people to report underage drinking, illegal drug use and other problems anonymously.

The public can text an eTip to 274637 or go to www.MidCoastCasa.org and download a free “TipSubmit Mobile” app from the Apple App Store or Android Market. The eTip program is available in Bath, Brunswick, Richmond, Arrowsic, Bowdoin, Bowdoinham, Woolwich, Topsham, West Bath, Phippsburg, Georgetown and Harpswell.
