"If you are on or near campus, go inside and avoid windows," the Town of Chapel Hill wrote Wednesday on X, formerly Twitter. 

Alert Carolina warned, "Emergency: Armed, dangerous person on or near campus. Go inside now; avoid windows." 

There were no immediate reports of shots fired, the university newspaper, The Daily Tar Heel, noted.

Chapel Hill Police announced that Mickel Deonte Harris, 27, was arrested at around 2:45 p.m. in relation to "an incident on UNC-Chapel Hill’s campus earlier this afternoon." 

Harris had outstanding warrants related to a Sept. 5 assault, police said.

The latest Alert Carolina update at 1:30 p.m. continued to warn of reports of an armed and dangerous person on/near campus. "Continue to shelter in place," it added. 

UNC Police wrote on X about reports of an armed and dangerous person, advising to "continue to shelter, silence your phones, and check http://alertcarolina.unc.edu for information."

In a message on Facebook, Chapel Hill-Carrboro City Schools (CHCCS) said it was aware of a 12:54 p.m. message from Alert Carolina that stated, "Emergency, Armed, dangerous person on or near campus. Go inside now; avoid windows."

This comes just weeks after Tailei Qi, a UNC Chapel Hill Ph.D. student who previously studied in Louisiana and Wuhan, China, was charged in the deadly shooting of an associate professor in a chemistry lab building. The shooting sparked a campus-wide lockdown and a manhunt before the suspect's capture.
