Officials with the Calvert County State’s Attorney’s Office said the harassment began in December and the students refused to stop despite repeated requests. The victim ultimately reported the behavior to Maryland State Police, which investigated and filed charges against the students.

The defendants, all 13, are students at Plum Point Middle School in Calvert County, which serves students in sixth through eighth grades and is located about 50 miles (80.5 kilometers) southeast of Washington, D.C. Their names are being withheld because they’re underage.

Officials said the charges will be forwarded to the Maryland Department of Juvenile Services for appropriate action.
