Cumberland County sheriff's deputies and Fayetteville police responded to a call for help shortly after 11 a.m.
Law officers began a search inside the building for three people who were believed to be armed. Deputies and police detained three suspects for questioning shortly after arriving at the school. No weapons were found.
Vernon McCray, 38, of 1226 Shaw Road had allegedly been chasing Darnell Williams, also of Fayetteville, along Country Club Drive. McCray told deputies Williams had broken into his home earlier this week. Williams said he feared McCray was armed and had run inside Westarea Elementary to escape him.
While at the school, police discovered an active 2005 warrant against McCray for unauthorized use of a motor vehicle and took him into custody.
There were no injuries at the school.
