Columbia, SC (WLTX) - Columbia police are investigating after a woman was shot at an apartment complex in the Harbison area Monday.

Officers say the incident happened before 11:45 a.m. at a unit along Harbison Station Circle. That's just off Columbiana Drive, about a mile from the Columbiana Centre Mall there.

Officers say the woman was seriously injured, and had to have surgery. The shooter ran from the scene, according to officers.

Investigators say they're following up on leads and collecting evidence from the apartment, but they believe the victim knows the shooter and the incident is isolated. They later said they were interviewing a person of interest.

Harbison West Elementary was briefly put on a lockout as a precaution. An officer was present at the school, and there were no reports of incidents at the school.

Anyone with information in the case should call Crimestoppers at 1-888-CRIME-SC.
