A Boston first-grader is being investigated for possible sexual harassment for punching another boy in the groin following a school bus fight, according to a report from MyFoxBoston.com.

Tasha Lynch, the mother of the boy, says her son was acting in self-defense after the victim allegedly choked him on a school bus and stole his gloves.

Lynch says her 7-year-old son was merely trying to protect himself, MyFoxBoston.com reports.

A spokesman for the Boston school system confirmed that an investigation was indeed underway, but would not discuss details of the incident, including why it had been classified as a sexual assault.

Lynch says her son is only being investigated because he punched the other boy in the groin. She argues that the other boy should be charged with attempted murder for choking her son.
