FAIRFIELD — A teenager who police say is part of a group of juveniles who for months have caused disturbances and other problems in Fairfield was arrested over the weekend following another complaint made to police about the youths’ behavior, according to officials.

The 14-year-old boy, whose name has not been released because he is a juvenile, was taken into custody after he harassed a person, refused to sign a police summons and turned combative, Chief Thomas Gould of the Fairfield Police Department wrote in an email Monday.

The boy was charged with disorderly conduct and harassment.

The incident began at about 2 p.m. Saturday, when police were called to the football field at Lawrence High School, where several juveniles were “being disorderly.” As officers were telling the group to leave the area, a second call came in reporting a man had been harassed and possibly threatened by someone in the group.

Police spoke to the 14-year-old boy, who was suspected of having made the threats, and issued a summons, but the youth refused to sign it and began swearing loudly, offending some of those who had gathered nearby for a family event.

Gould said the boy is part of a group of about a half-dozen teenagers whom residents have complained are causing increasing problems, such as harassing people and jumping in front of cars to stop traffic.

Officers arrested the boy, who afterward became so combative police used pepper spray to control him, Gould said. Members of the Fairfield Fire Department and Delta Ambulance responded, but could not immediately administer treatment because the teen was behaving so aggressively.

Once the boy calmed down and was treated, he was taken to the police station, where officers called juvenile probation and the boy was released to the custody of his parent. He is scheduled to appear in court Dec. 5 in Skowhegan.
