CONCORD, N.H. — A settlement is being worked on between the parents of a New Hampshire teenager who was tattooed against his will and the Concord School District.

Michael and Tammy Austin sued the district in 2011, saying officials didn’t do their jobs and could have prevented what happened to their son. The district denied the allegations.

Their son was a 14-year-old high school freshman in 2010. Police said four people were accused of tattooing a lewd image and words on his backside. They pleaded guilty to charges stemming from the incident and served between several days and six months in jail. Three were high school students; they were expelled.

The Concord Monitor reports Stephen Duggan, a lawyer for the Austins, said settlement negotiations are ongoing and there won’t be a trial.
