MURRELLS INLET, S.C. (AP) — A South Carolina high school has been evacuated for the day after someone burned several American flags outside the front entrance before classes started.

Officials at St. James High School in Murrells Inlet found the burned flags around 6:20 a.m. Monday and called Horry County Police. When investigators reviewed surveillance video, they say they saw the suspect do other suspicious things and decided to keep students and teachers outside.

A photo released by police shows a man with flags dressed in all black, including black rimmed goggles.

The students and teachers were eventually taken to St. James Middle School. Students aren't being allowed back on campus as police continue to check the high school.

So far, authorities say nothing else suspicious has been found.
