Police in Westerville have arrested a high school student following a threat of a school shooting scrawled on a Westerville South High School bathroom wall a week ago. Police say they used video camera footage, more than 60 student interviews and reviews of handwriting samples to identify a suspect. The student was charged with inducing panic and taken to the Franklin County Juvenile Detention Center following his arrest Monday. Police say the threat found a week ago on the bathroom wall warned students not to come to school Monday, saying there would be a shooting. Westerville Division of Police Lt. Jeff Gaylor says any threat to school safety is taken seriously.
