The YouTube video shows the teens being forced to stand against a wall while the officers question them. The video was shot by El Centro student Charlie Adams, who said he was just smoking a cigarette outside when the incident began on March 25.
The teens don't appear to be resisting arrest or causing problems for the officers. They said they were waiting for a bus.
"I got a lot of stuff on my belt that would take care of you this afternoon," one of the officers says on the video. "I guarantee you I will be glad to use some of it."
An officer pulls the teens' shirts up, frisks them and asks if they have drugs on them. Then her actions appear to turn physical, slapping one teen on the shoulder then yanking out his earphones.
"She hits him right there," said Adams. "Bam! What's your name? He answered her again. What's your name? He answered her again."
Adams posted the video to his YouTube page right away, then turned it over to an associate dean.
"She was just as shocked as I was," said Adams.
"Based on the footage we have seen, the Dallas County Community College District has launched a full investigation to determine all of the relevant facts," a Dallas County Community College spokeswoman said in a statement. "In the meantime, both El Centro College officers involved in the incident are on administrative leave."
The district will not release the official police report because the teens are minors.
Adams has seen the aggressive officer three times since and says he feared retaliation for outing her.
"I'm glad she's gone because I don't have that fear anymore," he said.
