SALT LAKE CITY -

Police say the recently crowned Miss Riverton, Utah, has been arrested on suspicion of throwing homemade bombs out of a car.

A report from the Salt Lake County Jail says Kendra McKenzie Gill, who was set to compete in the Miss Utah pageant, was taken into custody early Saturday, along with three others.

Police say the four admitted buying plastic bottles, aluminum foil and household chemicals before putting together the explosives and throwing them in neighborhoods. Nine incidents were reported, although police say nobody was injured.

The others arrested on suspicion of detonating an incendiary device were John Patrick Reagh, Shanna Marie Smith and Bryce Christopher Stone. It wasn't immediately clear if they had attorneys.

Stone reportedly told police that he and his friends were "pranking" with fireworks.

The South Valley Journal reports Gill won a $2,000 scholarship in the June 8 pageant. About 40,000 people live in Riverton, 20 miles south of Salt Lake City.
