RALEIGH, N.C. — The mother of an Enloe High School student has filed a complaint with the Raleigh Police Department after an officer threw her son to the ground Thursday as police responded to a water balloon battle at the school.

Seven students and a parent were arrested.

Sophomore Jahbriel Morris wasn't among those charged, but he had to be treated at WakeMed for a cut above his eyebrow, a bruised shoulder, a scraped knee and a sore neck and back.

Morris, 15, said he was injured when a police officer grabbed him outside the school, knocked him down and drove his head into the ground at least twice.
