Seven people were displaced by a fire this evening in the 200 block of South Street NE in Buford, according to Gwinnett County fire officials. About 6:13 p.m., a neighbor reported flames coming from an older single-story house and said there were two cars in the driveway. The caller said he did not know whether anyone was in the home, said Capt. Tommy Rutledge, spokesman for the Gwinnett County Department of Fire and Emergency Services.
