BATON ROUGE - Police have arrested two sisters, ages 13 and 18, after the two were seen on video pummeling a Baton Rouge bus driver. The pair's mother, who also got in on the attack, is still on the run.

The Baton Rouge Police Department announced Friday that the youngest sibling, a student at Kenilworth Science and Technology Charter, was taken into custody. Her sister, 18-year-old Carlicia Lewis was arrested Wednesday.

Lewis and her sister were booked for second-degree battery of a school bus driver. 

Their mother, Brittany Banks, faces similar charges. Both Banks and Lewis also face charges for contributing to the delinquency of a juvenile. 

A BRPD spokesperson said Banks was initially supposed to turn herself in Thursday morning but never showed up. A GoFundMe page that appeared to be set up by Banks indicated she was trying to raise money to pay for her bond before she turned herself in.

That page claims she jumped in after the bus driver "disrespected" her daughter and that she "acted like any concerned mother." 

The attack happened as the bus was stopped along Bradley Street at 5:30 p.m. Tuesday. 

Video posted to social media shows the confrontation happened after the driver got into an argument with a student, Banks' daughter. Police say that student then called for her mom, who boarded the bus and started attacking the driver.

Officers say the driver had injuries to her head, neck and shoulder. 

Sources suggested the bus was carrying students from Kenilworth Science and Technology Charter. The bus driver is said to work for First Student. They released the following statement.

"At First Student, the safety of our employees and the students we transport is a responsibility we take very seriously. We are appalled by the behavior captured in the video. We are thankful our driver was not seriously hurt. Given this is an active investigation, we are not in a position to comment further." -Jen Biddinger, First Student.
