The mayor of Brockton is facing assault and battery charges after he allegedly touched a high school student, according to a criminal complaint filed Tuesday in Hingham District Court.

The charges stem from a May 22 incident, when Mayor Moises Rodrigues allegedly put his hand around 17-year-old student’s waist and shoulder as she was marching in a town parade. The student, who was part of Brockton High School’s marching band, is not named in the documents.

A Massachusetts State Police investigation cited 13 witnesses in its report. According to the documents, the girl claimed Rodrigues grabbed her by the waist while she was playing her trombone. The girl told police in an interview on the day of the incident that “Rodrigues was whispering into her ear saying, ‘play this again’ and ‘do this again for me,’ as she attempted to push away.”

Rodrigues then let her go and grabbed a flag from a student in the color guard, the report said.

The incident became more public the following month, after the mother of the student confronted Rodrigues at Brockton High School graduation on June 6. The mother approached the stage where Rodrigues was standing, telling him to leave and reportedly saying “you know what you did to my daughter.”

The family of the girl obtained a temporary harassment prevention order against the mayor in early June, following the graduation. A Hingham District Court judge denied a request to extend the order on June 22, saying the family failed to meet the requirements to issue one. But the judge admonished the mayor for “unwelcome, offensive, and certainly unprofessional” behavior.

When interviewed by police, documents show Rodrigues said he was shocked by the allegation that he made a student feel uncomfortable, and that none of the interactions he had that day stood out to him.

“Rodrigues stated that the song the band was playing was called ‘Anchors Away,’ a Navy military song. As a Navy veteran himself, he acted as if he was being the conductor of the song as he was walking next to [the student],” the report said.

Rodrigues’ campaign website describes the 65-year-old mayor as a Cape Verdean immigrant and U.S. Navy veteran.

Rodrigues told police he had asked the deputy superintendent to apologize to the student on his behalf. The mayor said he then drove back to the high school to explain to band teachers that he meant no harm.

Rebecca Desmond, director of music for Brockton Public Schools, told police she spoke with the mayor following the incident.

“According to Rebecca, Rodrigues stated that in his culture (Cape Verdean) it was common for adults to put their arms around students,” the police report said. Desmond said she told Rodrigues that with her students, “it is best practice not to put your hands on a child because you don’t know how they will react or what trauma they have been exposed to.”

The music director told police that Rodrigues had an interaction with another student, a majorette in the parade, in which Rodrigues grabbed her baton and swung it around.

Marching band director Andrew Fantucchio also met with Rodrigues after the incident, according to the charging documents. He reported that Rodrigues wanted to apologize to the students, but Fantucchio told Rodrigues that he didn’t think that would be appropriate.

Prosecutors Tuesday filed a single misdemeanor assault and battery charge against Rodrigues in Hingham District Court. The charge was originally brought in Brockton, where Rodrigues has served as mayor since January. It was transferred to Hingham because of a “conflict,” according to court records.

Rodrigues’ arraignment is set for Sept. 28. His lawyer, Mark Lawton, was not immediately available to comment.
