OKLAHOMA CITY -- Oklahoma City Police are not taking any chances with security at the Oklahoma State Fair.
Authorities ran into someone they knew from a previous case and wasted no time closing in.
OKC Police Sgt. Jennifer Wardlow said they called in undercover agents Friday night.
"They knew that this man was a registered sex offender and he was actually working some type of a booth at the fair," she said.
Wardlow said a little more fact checking brought more concerns.
That's when police determined that 26-year-old Aaron Craiger was employed at the fair but had failed to check-in with his employer as a registered sex offender.
He was released in 2010 after serving time for five counts of second-degree rape.
"Our concern is this guy is a registered sex offender he's out there working at the fair," she said. "He's working around a number of people, including young children, at the fair."
Wardlow said Craiger was also suspiciously dressed.
"When officers came in contact with him he was wearing some type of a bond enforcement shirt," Wardlow said. "He was also carrying handcuffs and a badge. Obviously anyone who could have seen him could have mistaken him for a law enforcement official."
Craiger was arrested for police impersonation and failure to comply with the sex offender registration.
