A high school teacher from the Bronx is offering his students free jiujitsu classes.

Fernando Restrepo is a teacher by day and a martial arts instructor by night.

The Bronxdale High School teacher says it's a way to engage his students and keep them out of trouble.

Students in the class say they have become more disciplined thanks to jiujitsu.

The students meet twice a week for an hour and a half inside the school's gym at the Christopher Columbus campus.
