ANAHEIM, Calif. (AP) — Prosecutors have filed a felony charge against a Disneyland employee who allegedly detonated two so-called dry-ice bombs at the theme park.

Orange County district attorney's spokeswoman Farrah Emami say 22-year-old Christian Barnes will make a court appearance Thursday on one count of being in possession of a destructive device in a public place.

He is expected to be held on $500,000 bail, reduced from $1 million provisional bail.

Barnes is a vendor at the park. Prosecutors say he placed dry ice in two water bottles to make the so-called dry-ice bombs.

The first exploded in his vending cart.

Barnes is accused of putting the second bottle in a nearby trash can, where it exploded as a custodian was unloading garbage.

Barnes' father says his son just wasn't thinking.
