A West Forsyth High School student was injured Monday night after his vehicle overturned in a south Forsyth neighborhood.

The wreck occurred about 5:45 p.m. on Polo Drive in the Polo Fields subdivision.

Sean Morrison, 18, was taken to Piedmont Hospital in Atlanta, according to a Forsyth County Sheriff’s report.

The report does not describe the injuries the teenager suffered in the wreck, but shows that he was cited for improper backing.

The crash occurred Monday as authorities were fielding calls from residents complaining that objects were being thrown from one or more vehicles traveling through the neighborhood.

According to the report, Morrison had been “backing away from his friends, who were chasing him on Polo Drive.”

The report noted Morrison had attempted to back into a driveway in a 2005 Jeep Wrangler when he apparently misjudged the distance and struck a brick mailbox.

The Jeep climbed the mailbox and flipped over, the report shows.

A 17-year-old passenger was not injured.

Another passenger, 18-year-old Reid Steckenrider, said he got out of the Jeep just before the crash because female classmates were chasing them in another vehicle.

“They were throwing eggs at us and I was in the back seat,” he said Monday night at the scene, adding that his position made him a primary target.

Steckenrider explained that the chase was part of what students call the “junior/senior wars.”

Juniors and seniors pull pranks on each other in the days leading up to the school’s annual homecoming, he said, adding that such activities are not condoned by school administrators.

West’s homecoming is Oct. 7 against Northview.
