Salisbury High School has made changes to this week’s athletic events because of “recent incidents” that have occurred near the school, its principal said.

The incidents were off-campus and not related to the school, Principal Luke Brown said in a letter sent out to parents on Tuesday.

Brown did not specify what the incidents were. There have been three shootings near the campus recently.

On Wednesday, a tennis match was moved to East Davidson High School and a soccer match to Thomasville High School. Both were scheduled to be played at Salisbury High School.

The letter also stated that Friday’s varsity football game against Surry Central High School will be held at 6 p.m at Ludwig Stadium. The game had been scheduled for 7:30 p.m.

Brown also said law enforcement would be present at the school so the community can continue to come out to events.

“We will continue to work closely with law enforcement, as well as our staff, students and parents to ensure that we maintain a safe and secure campus,” Brown stated in the letter.

Three shootings have occurred near the Salisbury High campus in less than two weeks. The first was Sept. 12, the others followed Sept. 17 and 18.

The Sept. 17 shooting happened during a football game between the Salisbury High and Ledford High junior varsity teams, leading officials to end the game early.

Two other shootings occurred Sept. 16 and Sept. 19 near Martin Luther King Jr. and Park avenues.

Authorities say they believe at least some of the shootings were gang-related and the people involved knew one another. The violence was not random, Salisbury Police Department Capt. Sheila Lingle said this week.

The Police Department and Rowan County Sheriff’s Office announced they would work together to combat the violent crime.
