Freeman stated that the matter will now be closed without further action."Our law enforcement officers are engaged daily in difficult interactions where they often are required to intervene. As they strive to maintain the peace and protect our community, it's important that proper and legal boundaries on the use of force are followed," said Fereman. "I commend Chief of Police Bobby Langston for his willingness to invite an unbiased review of this matter and for his commitment to maintaining the public trust of his community."The teen was returned to class after the incident, but then later taken to the hospital for treatment of a concussion.De Los Santos resigned from the Rolesville Police Department earlier this month.
