Seven people have been charged in connection with graffiti and vandalism at a historic site in Massachusetts.

Hull police Chief Robert Sawtelle says an officer spotted vulgar and racist language spray painted on the walls at Fort Revere in Hull early Friday morning. She located a group of teenagers nearby that had bottles of spray paint in their possession.

Four 18-year-olds and three 17-year-olds were charged with tagging, malicious destruction of property and trespassing. They will be arraigned next week.

Town and state officials funded the repainting of Fort Revere in June to remove graffiti. Police have since increased patrols there.

Fort Revere Park is a historic site located atop Telegraph Hill containing the remains of two seacoast fortifications in Hull, which is on a peninsula in the Massachusetts Bay.
