POLK COUNTY, Fla. -

A high school principal and three women who traveled to the area to make money during the Republican National Convention are among 89 people arrested by Polk County sheriff's detectives in an online prostitution sting investigation.

Kathleen High School Principal Cecil Edward McClellan was arrested in the week-long sting.

"We are extremely disappointed in this news. However, our No. 1 focus will continue to be on providing our students with a quality education and providing our school faculty with the support they need. Kathleen High School is an award-winning school and I expect no less in the future," said Dr. Sherrie B. Nickell, superintendent of Polk County Public Schools.

Polk County sheriff's released undercover video of McLellan walking into a hotel room, taking off his shirt and touching the decoy prostitute.

"I can tell you this is devastating because Cecil was well-respected in the education community and for him to have a misstep like this was just so unlike him," said Polk County Sheriff Grady Judd.

The 89 suspects were charged with crimes ranging from soliciting prostitution to drugs to battery on a law enforcement officer.

One man from Orlando also faces charges accused of traveling to Polk County to have sex with what he thought was an 11-year-old. Three women were also arrested for traveling to the area in hopes of making money during the RNC.
