Authorities in Tennessee say a 15-year-old high school student set his teacher's hair and clothes on fire during class earlier this week, the Gawker website reports today (November 29, 2013).
Gabriela Penalba -- a science teacher at West High School in Knoxville -- had her back to the classroom when the teen snuck up behind her and ignited her hair and shirt with a lighter.
Students rushed to the 23-year-old teacher's aid, helping her extinguish the blaze, thus avoiding serious burns.
The student tossed the lighter out a nearby window and fled, but was soon caught by school resource officers. The suspect was charged with aggravated assault and evading arrest, and was transported to a juvenile detention facility.
