ORANGE COUNTY, Fla. -- Students said a man threatened to shoot everyone on an Orange County school bus Friday afternoon after bus passengers apparently threw something at his vehicle, according to Orange County sheriff's deputies.

According to a transportation official with the Orange County School District, the Robinswood Middle School bus was taking students home when the incident happened Friday afternoon. Two students on the bus were apparently throwing something out the windows when a passing driver was able to stop the bus, at which point students said that driver made a threat to shoot them.

Deputies, however, spoke with the accused driver and said he had no weapon. He was allowed to leave the scene and no charges were filed. Investigators said he was actually the person who called police.

Meanwhile, the two students accused of throwing things from the bus window took off when the bus stopped following the incident and they have not been located.
