— Seven students and a parent were arrested Thursday at Enloe High School in Raleigh after an end-of-year prank caused commotion on campus, authorities said.

Kevin Antrone Hines, 38, of 105 Shalon Court in Apex, faces one count of second-degree trespassing.

Enloe student Justin Mangum Devon, 17, of 2108 Walnut Bluff Lane in Raleigh, was charged with assault and battery.

Six students were each charged with disorderly conduct:

Roderick Elliott Hodge Jr., 16, of Barwell Road, Raleigh

Kelton Treyquan Hines, 16, of Brintons Mill Lane, Knightdale

Christopher Montrell Coward, 17, of Calumet Drive, Raleigh

Robert Edward Brown, 16, of Waterford Landing Court, Raleigh

Damarcus Nathaniel Cole, 16, of Gladstone Drive, Raleigh

Deonte Rodricus Ward, 16, of Frenchmen Court, Raleigh

Cole was also charged with resisting a public officer. He was in the Wake County jail Friday morning under a $3,000 bond. Mangum and Ward were also remained in custody Friday.

Hodge, Kelton Hines, Kevin Hines, Coward and Brown were released late Thursday, authorities said.

In a message to parents, Principal Scott Lyons said students had planned "several pranks on campus," including throwing balloons filled with water and other substances at other students.

Russ Smith, senior director of security for the school system, said school officials are taking the incident seriously.

"Somebody gets hit with a water balloon. They don't like it. So, the potential is there for there to be a physical altercation," Smith said.

Teachers and administrators kept students in their classrooms during seventh period as a precaution, he said.

A school system spokeswoman said one Enloe student was hospitalized after being bitten by a snake at the school. It wasn't clear whether that injury was related to the pranks.
