Davidson and Charlotte-Mecklenburg police searched an area of east Davidson near N.C. 73 Wednesday night for a young man who called police and was threatening to hurt himself. The man was unarmed, but police were warning residents to be wary and not to respond to unexpected knocks at the door.

The incident began around 9 p.m., when police received a call from the teen. As of 11 p.m. police on the ground and in a CMPD helicopter were still searching an area around N.C. 73 and Davidson-Concord Road and nearby streets, including the Pages Pond neighborhood and the area near the entrance to the River Run neighborhood.

Police don’t know the teen’s identity, though the head of the Pages Pond Homeowners Association told neighbors in an email that CMPD knew his first name. He was not armed, Chief Miller said.

Chief Miller said the man has a history of mental health issues. He reportedly left his home earlier in the evening with potentially harmful medications and was threatening to take them.

Although he is not threatening to harm others, Chief Miller advised residents to keep an eye out, and report sightings of the man or other suspicious activity by calling 911.

No further information was available.
