BROCKTON, Mass. -- It's a case of sexual harassment -- involving first-graders.

A boy at Downey Elementary in Brockton, Mass., was suspended from school for three days last month after school officials said that he sexually harassed a girl in his class.

Elementary school officials called the boy's mother, Berthena Dorinvil, on Jan. 30, and asked her to pick up her child from the school. Dorinvil said that officials told her that her son was being suspended for sexually harassing a 6-year-old female classmate.

"My son told me that the girl touched him first, so he touched her back," Dorinvil said. "I was shocked. I was crying. I was out of control," Dorinvil said.

Dorinvil said she "screamed' when she heard about the disciplinary action.

Dorinvil said the boy is just 6 and has no idea what sexual harassment means. Dorinvil said her son wanted to know if the police were going to take him away.

"When he comes home, he says, 'Mommy, are police going to arrest me?' I can't even make a phone call without him (asking) who I am speaking to. He is very frustrated because he is a very emotional kid. It bothers me so much to see my son go through this," Dorinvil said.

Dorinvil said the children were playing on the floor and touching each other. She said her son touched the girl's shirt, but not her skin. She said her son was suspended after being accused of putting two fingers inside the female classmate's waistband and touching her back.

Dorinvil is outraged and has demanded that her son be transferred to another elementary school.

The suspension has ended but Dorinvil has not sent her son back to the school. She wants him moved to another school, but so far officials have only offered to move him to another class within the same school.

Brockton school officials are defending their decision to suspend the first-grader.

School officials would not speak on camera, and police officers were posted at the school Tuesday afternoon. The school superintendent released a statement that said, "The safety and well-being of Brockton public school students and staff is of the utmost important to us, and we take all allegations of sexual harassment seriously."

But Dorinvil said her son has no idea what the term sexual harassment means and insists he was only playing with the girl.
