MIAMI -- An Ohio man is under arrest for revealing a bizarre sexual plot to an undercover investigator online, then flying to Miami, according to Florida's attorney general.

Investigators said Jeff Doland, of Uniontown, Ohio, was arrested on felony charges that he approached an undercover agent online and offered to pay to act out his sexual perversions with children, said Attorney General Bill McCollum.

Doland was arrested by authorities after he flew to Miami to meet a mother of two girls. Doland told the woman he would pay the woman $550 to "forcibly submerge the children, ages 9 and 12 years old, under water until they became unconsciousness, then raising the person out of the water."

During multiple internet conversations, Doland told the woman, an undercover agent with the United States Secret Service, that "dunking" was his particular form of sexual gratification.

"The allegations made during the course of this investigation are so heinous they are almost outside the realm of comprehension. Without law enforcement intervention, real children could have been in grave danger," said McCollum.

McCollum said Doland claimed he "liked watching the bubbles" and went on to send the undercover agent explicit images of child torture as examples of what he proposed to do to the two young children, including a detailed explanation of how he planned to bind the young girls to the bottom of the pool of water.

Doland was arrested when his plane arrived in Miami.

Doland will initially be charged with selling or buying of minors, a first-degree felony, and promoting the sexual performance of a child, a second-degree felony. Doland faces up to 45 years in prison for the charges against him.
