From Las Vegas: A dramatic scene unfolded at a school crosswalk. People were crossing the street when a vehicle sped toward them. A guard intervened, stepping into the path of the oncoming car. The guard was holding a child's hand at the time. The incident involved a mother and her two children, who were apparently unharmed.

Details of the event are available from dashcam video. The video was captured last Wednesday morning. It shows the guard's actions, which are credited with helping to prevent an accident.

Further information about the incident can be found through the original report.
