NORTHERN PALM BEACH COUNTY, Fla. - The Palm Beach County Sheriff's Office arrested Sean Kowlessar after they say he had an inappropriate relationship with a 14-year-old student.
The sheriff's office says Kowlessar is owner and lead instructor at Lake Park Martial Arts, which its website says is located in North Palm Beach.
"No way! I can't believe this," Carmen Correa said as she was trying to drop her granddaughter off at the martial arts studio Thursday.
Correa says she never suspected anything strange.
A sign on the door said,"Due to an emergency, the DOJO is closed."
PBSO investigators say the alleged 14-year-old victim came to karate class three times a week for the last year.
Investigators say Kowlessar started leaving the teen inappropriate messages in a bathroom drawer, then started sending her sexual messages and pictures to her iPod touch.
"He was wonderful with the kids. Everyone, even with the moms and dads and everyone liked him," Correa said.
During a controlled phone call, detectives say Kowlessar said the messages were "horribly inappropriate. Every single thing was inappropriate."
Detectives say any parents who think their child may have had inappropriate contact with the teacher should call PBSO.
Kowlessar remains behind bars.
