A teen accused of fatally stabbing a classmate and injuring another after allegedly sneaking a switchblade into a Bronx school appeared back in court Thursday.

Abel Cedeno was indicted on manslaughter charges after prosecutors say he fatally stabbed 15-year-old classmate Matthew McCree and injured 16 year-old Ariane Laboy at the Urban Assembly School for Wildlife Conservation in September of last year. 

There were no metal detectors inside of the school, and prosecutors say the teen was able to conceal the switchblade.

Both family members of Cedeno and McCree appeared inside the courtroom Thursday where the judge presided over the case.

A lawyer for Cedeno says his 18-year-old client is maintaining his innocence, and says he was bullied for his sexual orientation by the two teens.

Meanwhile, McCree’s family says Cendeno's defense team has made false claims that their slain son was involved with gangs.

McCree’s mother publically stated that her younger son is now being questioned by alleged gang members and that he doesn't feel safe. 

Cedeno is currently out on bail and is expected back in court on March 6.

The Department of Education announced a plan to close the Urban Assembly School for Wildlife Conservation months after the stabbing.
