TULSA, Oklahoma - A prostitution arrest at a south Tulsa business has some officers thinking it could be a case of human trafficking.

South Tulsa business owners say Sun Spark Foot Massage has only been there a few months, that most of the clientele were men and that they had a weird feeling about the business.

Popular shops, restaurants and businesses fill the 101st and Sheridan area. Magness Fitness is one of the newest residents – something Skye Magness and his wife have been dreaming of opening for years.

"We exist to provide one-on-one personal training - kind of a safe haven for people who might not be gym rats who kind of wanna accomplish their goals in a private setting," he said.

Two doors down from their shop is Sun Spark Foot Massage.

It was closed Wednesday, less than 24 hours after an undercover officer said he was offered sex acts for money by one of Sun Spark's employees.

"It's nothing but frustrating from the business side of things,” Magness said. “It's a major concern because I want my clients to feel safe, but, from a personal standpoint, it's more what can I do to help."

Tulsa Police Sargent Todd Evans said officers received a tip, started investigating, and that’s when they noticed the business getting reviews on adult websites from men claiming they were receiving sex acts for money.

An undercover officer walked into Sun Spark Foot Massage and said he was offered sex acts for money. When the officer told the woman, Jessica Lin, she was under arrest, she ran. Police caught her a few blocks away.

Evans said Lin and her co-workers were questioned Tuesday night and are now investigating the possibility it’s a case of human trafficking.

“Neither one of the employees had any kind of identification on them, it appeared neither employee was licensed to do massage by the state, neither one of the employees had their passports, they were unable to provide information as to who owned the business or who they even worked for," he said.

Evans said those are all red flags that the girls might be victims of human trafficking. However, he said, at this point, he’s not sure Lin will cooperate with police.
