An Oklahoma mother is outraged after she said a group of boys attacked her 5-year-old son.

A Tulsa Public Schools spokesperson said the district is investigating after a Skelly Elementary School kindergartner was allegedly attacked by three other boys at the bus stop at his apartment complex. His mother said the boy is scared to go back to school.

“When I got him he looked terrified,” said the boy's mother, Brittani Botello.

Botello was pulling into the apartment complex when a school bus dropped off her son.

“I’m looking around and I’m not seeing him,” Botello said.

Another mother flagged her down and said her son had been attacked.

“He has two chipped teeth. He has marks on his face. His lips are swollen,” Botello said.

Her son and another student told Botello that three older boys had jumped him after they got off the bus.

“I was very angry when I picked him up and saw his face. He’s 5 years old. He can’t defend himself,” Botello said.

“It’s just very upsetting that kids would do that to a 5 year old,” said Chris Payne with TPS.

Payne said the district is trying to find the children involved and said they could face disciplinary action at school.

“It’s just heartbreaking to see the bullying of a child at such a young age,” Payne said.

Botello said her son doesn’t know why he was attacked.

“Me and the police officer asked him, ‘did you know why they hit you’ and he just said no. They just said, ‘we don’t like you,’ and attacked him,” Botello said.

The district is letting Botello’s son transfer to another school. She said her apartment complex will also have security drive around when students are getting off the buses.
