A school bus security camera recorded middle school boys groping girls and engaging in simulated sex that apparently went unheeded by the bus driver.
Seven Forest Oak Middle School students, 12 to 15 years old, were suspended for their actions seen on the videotape. Four of those are being investigated for possible indecency, the Fort Worth Star-Telegram reported Tuesday.
The videotape of the Sept. 15 incident showed disturbing scenes of boys groping girls' breasts, holding the girls down and simulating sex acts.
In one case, a boy wrapped his legs around the girls' heads.
The video also shows one boy being struck by a rock and appearing to be in pain as other children lie face down in the aisle and seats to avoid getting hit by flying debris. Several punches also are thrown.
Authorities said the boys denied doing anything. When they and their parents were shown the video, they said nothing, police said.
Cynthia Fowler, the bus driver, complained only after some of the children hurled rocks and football-size chunks of dirt and grass into the vehicle, police said. She has been suspended with pay pending an investigation.
