A 15-year-old Ravena-Coeymans-Selkirk High School student is facing several charges for allegedly writing a bomb threat on a bathroom wall at the school on March 9. Coeymans police last week arrested the teenage boy, whose name is not being released due to his age, and charged him with making a terroristic threat and falsely reporting an incident in the second degree, both felonies, along with obstructing governmental administration, making graffiti and criminal mischief in the fourth degree. The teen was sent to the Capital District Juvenile Secured Detention Facility pending further Family Court appearances, according to police.
