A 12-year-old girl has been arrested and charged with phoning in a bomb threat that emptied Warren Central Junior High School Wednesday morning.

The girl, a student at the school, made the call at 9:38 a.m., said Vicksburg Police Capt. Mark Culbertson, and was arrested at 1 p.m. She was being held in the Warren County Juvenile Detention Center.

She did not give a reason for making the call, Culbertson said.

The threat was the third in two days at Warren and Vicksburg junior high schools, which are next door to each other, and the fifth evacuation of a local school in five days. Both junior highs were evacuated Tuesday after bomb threats were called in by a person described only as a male.

In the first in the series of forced evacuations, Friday at Warren Junior, a student was charged with setting a roll of paper towels on fire in a boys’ restroom. Another evacuation at the same school came Monday after administrators said they smelled smoke, and the source turned out to be an electrical problem.

In a separate arrest at Warren Junior Wednesday, a 15-year-old was charged with sale of marijuana.

The boy was arrested at 2:04 p.m. after an investigation, Culbertson said.

He was also being held in the Warren County Juvenile Detention Center.

The students could face a long-term suspension or expulsion, said Superintendent James Price. They will appear before a district discipline committee when they are released from the detention center, Price said, and the committee will hear evidence and make a recommendation to the school board, which will make the final decision on action.
