ROY -- A father was charged with criminal mischief and booked into Weber County Jail on Sunday night after he appeared to be trying to throw his daughter's friend off a canal bridge, officials say.
Utah Highway Patrol Sgt. Brad Horne called the action an "absolutely, very poor decision."
Horne said both the man, who was in his 50s, and the woman, in her early 20s, said they were pretending. But he said that story didn't matter after what he and a half-dozen other people saw.
They saw the man dragging the woman 40 feet from a car toward a bridge as she was kicking and screaming.
The incident, near the northbound exit of Interstate 15 at 5600 South in Roy, occurred around 8:30 p.m.
Horne said he was leaving the freeway and was going to get back on to head in the other direction when the car pulled over in front of him and the man got the woman out of the car.
"We believe it probably was a spoof," he said. "You just can't joke around like that."
Horne said a handful of police responded to the call and that traffic was impeded for about a half-hour.
There also were reports Sunday night of a woman trying to jump from a vehicle on I-15.
Horne said officials were unsure if the incidents were related, and police were investigating to see if they were.
