UPPER DARBY, Pa. (CBS) — Haverford Township Police were called after a bus ride home from school turned chaotic Tuesday.

You can see at least one student jumping up and down on a moving school bus, while others are screaming, cursing, banging on the seats and threatening an Upper Darby school bus aide.

“What if I got a gun and put it right in your f**** face?” is said by one of the students.

The 14 minute video, taken Tuesday afternoon, was posted on YouTube by one of the students on the bus.

School bus aide: “Put up the window, move out the way. Get your hands off me.”

Student: “Get your hands off me, I didn’t touch you.”

School bus aide: “Yes you did!”

Student: “No I didn’t.”

School bus aide: “You did! Tim call security … I can’t take it anymore. I’m all stressed out.”

The bus driver did call 911 and eventually pulled over, at Upland and Shellbourne Roads. When the Haverford Township police showed up, they questioned two of the children.

The one causing the most problems told police, he’s only 7-years-old.

The children were eventually taken home, according to school officials and the bus aide was replaced at that stop, with someone else.

On Thursday morning, a spokesperson from the district issued a statement:

“The Upper Darby School District is aware of the troubling incident that occurred on an Upper Darby School District bus on May 14, 2013 involving students attending schools outside of the School District. The School District is also aware that video of the incident has been posted on You Tube. The School District has contacted You Tube and requested that the video be removed because of the age of the involved parties. The District is working with local law enforcement, the District Attorney’s office and other County agencies to address this issue and ensure the safety of the children in our schools and those the District is required to transport from schools outside of the District.

To the extent that the School District is allowed by law to publicly address these matters, it will post updates on its website.”

Officials say the bus was carrying 11 students, seven from Upper Darby and four from Haverford Township, all of whom go to schools outside of the district they live in.
