"So you still went for that, to have sex with him, knowing he was 15 years old?" the detective asked.

"Yes," Treaster said.

Treaster did not return calls from CNN.

He was one of four Disney employees and one Universal employee arrested in sex stings or in child porn cases from June 10 to July 1.

Previous arrests include:

• Cedric Cuthbert, the night shift custodial manager at Disney's Port Orleans resort, who was downloading child porn last year on his work computer while writing a sermon for his church, where he was the pastor, according to police. Cuthbert pleaded no contest to the charges and was sentenced to six years in prison.

• Paul Fazio, who worked in an Animal Kingdom Lodge gift shop. Fazio was convicted of downloading videos showing "multiple scenes of nude prepubescent children engaging in sexual activity with adults and other children," the police report said.

• William Marrero-Maldonado, who worked for Disney security. He was arrested in April after an Osceola County Sheriff's Office investigation claimed that he was downloading child porn videos. He has pleaded not guilty.

In the February sting by the Lake County Sheriff's Office, police also arrested 32-year-old Patrick Holgerson, another Disney employee. Holgerson sent nude photos and engaged in explicit sexual chats online with someone he thought was a 13-year-old boy and his uncle, according to police records. After he showed up to meet the boy, Holgerson ran from police.

During a videotaped interview with sheriff's detectives after the arrest, Holgerson said he was a character actor at Disney and in training to become a VIP tour guide.

He pleaded not guilty and said he went to the home to make sure the boy was OK.

"I work with kids," Holgerson told the detectives during the videotaped interrogation. "I love kids and not in a bad way. I just have a strong connection with kids. I like working with kids. I just enjoy helping them grow and that's why I've been working with high schools for so long is because a lot of these kids look up to me.

"And that's why I was honestly worried about this kid. Because I felt his uncle was in the wrong. I would never do anything with the kid, I promise. I didn't want him hurt. And I'm being honest here."

The sprawling Disney theme park has about 70,000 employees.

In a statement to CNN, Disney spokeswoman Jacquee Wahler said, "Providing a safe environment for children and families is a responsibility we take very seriously. We have extensive measures in place, including pre-employment and ongoing criminal background checks and computer monitoring and firewalls.

"The numbers reported by CNN represent one one-hundredth of one percent of the 300,000 people we have employed during this time period. We continue to work closely with law enforcement and organizations like the National Center for Missing and Exploited Children as we constantly strengthen our efforts."

Universal Studios said it fired Matthew Cody Myers, who was arrested in the July sting by the Polk County Sheriff's Office after police say he showed up to have sex with a 14-year-old girl. He told detectives during an interrogation that he wouldn't have really gone through with it. He pleaded not guilty, and did not return CNN's calls.

In a statement, Universal Studios spokesman Tom Schroder said, "We have zero tolerance for this kind of activity. We deal with situations such as this immediately and permanently." The company, like Disney and SeaWorld, requires that "all our team members undergo thorough background checks as part of the hiring process."

SeaWorld spokesman Nick Gollattscheck said, "The safety of our team members and employees is our top priority," adding that the company has "policies and procedures in place and we need to take appropriate action as needed."

Grady Judd, the sheriff of Polk County, Florida, said Disney and other businesses that cater to children need more leeway to use polygraph tests when hiring employees.
