A 92-second video posted to Facebook shows five children running, swearing, spitting and punching fellow riders on a Philadelphia-area train last Thursday night, as the woman who was supposed to be their caretaker could not keep them under control.
The kids' parents expressed shame and anger, according to WPVI-TV.
"I'm very ashamed," said Aurelis Rivera, the mother of two boys, ages 8 and 10, seen in the video. "I would never think they would do something like that."
Eulid Perez, the father of two boys, ages 7 and 11, and an 8-year-old girl, said that although he's not surprised by the language his children were using because of the area in which they live, he's still upset.
"It gets me angry, you know," Perez said. "I was angry at my kids, I'm still angry at my kids for acting like that."
Rivera said she feels awful for her children's behavior.
"And I just want to apologize for everybody that seen that video," she said. "I want to apologize to the man that went through that."
Fox 29 reported it could not contact the passenger who shot the video.
