LILBURN - A Berkmar High School student was injured Tuesday morning when he was cut by another student during a fight in the boys' bathroom, school district officials said.
The teens, who arranged to meet for the fight, face criminal charges of affray and disruption of a public school, district spokeswoman Sloan Roach said. The boy with the knife also faces charges of aggravated assault and carrying a concealed weapon, Roach said.
Breiner Alejandro Martinez-Londono, 17, of Lawrenceville was being held Wednesday in the Gwinnett County Jail, officials said. Police seized the 3-and-a-half inch knife he allegedly used in the fight.
Efraim Ruiz, 18, of Norcross - who was identified as Efrain Ruiz on a school police report - was taken to Gwinnett Medical Center for treatment. Roach said he was released from the hospital, but a Gwinnett County Sheriff's Department spokeswoman said Ruiz hasn't been booked into the jail since March.
The high school senior has been jailed twice in the past year, according to arrest records.
Ruiz was arrested during a January traffic stop on a charge of obstruction of a law enforcement officer, records show. He was also cited for underage possession or purchase of alcohol and driving with no tail lights.
The 18-year-old was arrested again in March on charges stemming from an armed robbery at an apartment complex, records show.
Ruiz is accused of robbing a man at gunpoint at the Northridge Apartments in Norcross and stealing his car.
The teen was arrested in Lawrenceville and charged with theft by receiving, theft by taking and obstruction of a law enforcement officer.
Ruiz was indicted Oct. 10 on those charges and is awaiting trial, according to court officials.
The Sheriff's Department has no record of past arrests for Martinez-Londono.
