Houston police said they took a man and woman into custody after a road rage incident in front of Fondren Middle School.
As hundreds of students were sitting in class Friday morning, officers said the fight happened outside.
Investigators said a 44-year-old woman was dropping her children off at school when she noticed the driver of an 18-wheeler get out and walk up to her.
Police said the woman claimed the 50-year-old man accused her of cutting him off on the road. The woman told police her 15-year-old son jumped in to defend her and started arguing with the truck driver.
The woman told investigators the truck driver went back to his 18 wheeler, pulled out a bat and started threatening her family.
Police said the truck driver told a different story.
He claimed he got out of the truck because he thought the woman stopped to apologize. The truck driver told officers he only got the bat to defend himself against the woman's son who started yelling at him.
Investigators said the truck driver was taken into custody for potential charges of assault by threat. Officers said the woman was also taken into custody because she had warrants out of Bellaire.
Fondren Middle School officials said they sent a letter to parents alerting them of the fight and assuring them no students were harmed.
The incident left some parents frustrated.
"It's just a sad state of society," said parent Raymond Peralez. "Everybody's just getting mad and not taking a deep breath and not talking it out. My wife could be dropping my kids off and it could happen to her."
"That's bad because children are going to act like we act," said parent Emma Judson, "And if we don't behave they're not going to behave. I'm glad my son was inside because I make sure he's inside before I leave in the morning."
