A mother caught on camera fighting with a 17-year-old Flagler Palm Coast High School student is changing her tune.

Felecia Phillips said Thursday she now regrets "laying hands" on the student. Flagler County deputies arrested the 35-year-old after she fought with a teen on a school bus Wednesday morning.

Wearing sunglasses to shield her emotion, Phillips, a mother of two admitted her conduct caught on the school bus survellience video is unacceptable.

"I wasn't really thinking it was just the bus, you know, just out of -- I'm upset. I mean, I made a mistake," Phillips said.

Phillips said she regrets getting physical with the student but stands by her motive to protect her son, who she claims is frequently bullied by the older boy.

"I will defend anyone that's getting bullied or someone is picking on, that's just my character," Phillips said. "Not saying that I would do it in that way, but that's just been me since I was a child."

According to investigators, the fight started at a bus stop and eventually stopped there. Deputies said Phillips confronted the 17-year-old, then chased him onto the bus, actions the school district calls inappropriate.

"It's never a good idea for the parent to get on the bus," said Mike Judd, of Flagler County Schools. "If they need to talk to the driver, talk to the driver through the window, through the open door, but don't get on the bus."

The district points out that none of the so-called "bullying" between the boys took place at school.

Phillips said she acknowledges it's mostly in the neighborhood.

Despite watching his mom pushing and shoving, Terez Smith still stands by her.

"I'm not saying it was good for her to put her hands on him, but at the same time, she stood up for me," Smith said.

Phillips is charged with child abuse and trespassing on school property.
