Columbus firefighters said a smoke investigation at the Wal-Mart on 735 Whitfield Drive was caused by an electrical malfunction.

Firefighters were called to the store at 1 p.m. today after a customer reported light smoke coming from a refrigerated meat counter display rack, said Capt. Mike Wilson, Columbus Fire Department spokesman.

Firefighters found an electrical short in the meat counter light and used a dry chemical fire extinguisher on the combustible materials, and disconnected the power to the area.

Damages were estimated to be less than $500 and the store remained open during the incident.

No injuries were reported
