Authorities: 5 Suspected Arsons Set in North Carolina City

Investigators say they are looking into five fires that were intentionally set in the same area of Charlotte, N.C.

Fire department spokesman Rob Brisley says the fires started at around 4 a.m. Sunday and were set throughout the morning.

Brisley says the worst fire was at a tire store. Firefighters worked for about 30 minutes to put out the fire, which caused about $30,000 in damage.

Officials say two other fires were set inside a dumpster behind Waddell High School.

Investigators are looking at surveillance video from the school and nearby businesses to get clues about how the fires started.
