BARTOW, Fla. -

A Florida teenager who was accused of igniting a chemical explosion on school grounds -- and who became the subject of a social media campaign on her behalf -- will not face criminal charges.

Kiera Wilmot was arrested April 22 for two felonies after school administrators reported she combined toilet bowl cleaner and aluminum foil in a bottle, and the resulting gas blew the cap off the plastic bottle.

The Polk County State Attorney said Wednesday that the case has been dismissed, but the 16-year-old must complete a diversion program.

Details about the program aren't public record because Wilmot is a juvenile.

The teen's arrest launched an international outcry on social media by people who thought the arrest was unfair. Nearly 200,000 people signed an online petition protesting her arrest.
