An argument at a bus stop in Atlanta turned into a violent family affair, leaving one student stabbed and another sought by police, along with his mother and sister, authorities said.

The victim and another student, both of whom were not identified, got into an argument as they were getting on a bus en route to Bunche Middle School on Friday, the Atlanta Journal-Constitution reports.

That prompted the mother and sister — identified as Taza Danielle Harris, 44, and Chelsea Monicque Harris — to get involved, arguing with the other student and “getting in his face,” according to a report by an Atlanta Public Schools police officer.

“The students [at the bus stop said] the older sister swung on the [victim’ but missed as he was trying to get on the bus,” according to the report.

The victim then turned around and threw his book bag at Chelsea Harris before both women attacked the boy — one of them allegedly stabbing him with a knife.

The boy, according to a police report, was bleeding from his head, right hand and right ear when police responded to the scene. He was taken to a hospital, where he received stitches for the lacerations.

Both the victim and Harris’ son were not identified by school officials.

No other injuries were reported. In a letter sent home to parents, the school’s principal said the focus was student safety and well-being.

Calls seeking additional comment on Thursday from Atlanta Public Schools were not immediately returned.

Taza Harris, according to the Journal-Constitution, has previous arrested dating back to 2006, including busts for cruelty to children, battery, aggravated assault and gang charges. Chelsea Harris was arrested in 2012 on third-degree forgery charges, records show.
