Police said they expect more people to be charged and reported to prosecutors.
Chief Inspector Shaun McKillop said: "These are not random incidents but are incidents that have taken place between small identified groups of people.
"Such behaviour will not be tolerated and the local community can be assured that officers are following all positive lines of inquiry to ensure that all those responsible, both youths and adults, are identified and held to account."
Extra uniformed patrols and a mobile CCTV van have been deployed in the area.
Officers want to speak to anyone who was in the Dryburgh area at the time and may have witnessed the disturbances or who may know the people involved.
