Security heightened at Bartram High School

Security has been increased at Bartram High School in Southwest Philadelphia as part of a new plan to reign in violence.

Four additional Philadelphia and school police officers began patrols at the school on Monday morning.

Ozzie Wright is also starting as Batram's new co-principal. Wright is known for his success in troubleshooting at schools.

This comes after cell phone video emerged of a large fight in the school, and after a student knocked out a staffer put in place to deal with conflicts.

A local lawmaker said schools must be havens of discipline.

"The goal for the day is zero tolerance and to make sure the students in there understand that school is a place to come to, where they have systems in place, they have rules in place," said Rep. Ron Waters (D-Philadelphia).

The district has disciplined the students involved in that brawl.

School officials hope to get social services help for students who need it.
