VIDEO: Massage businesses allegedly running human trafficking and prostitution operations in Indiana

ST JOSEPH, Ind. (CBS) - Human trafficking, sexual solicitation, and tax fraud – all of those suspected at four St. Joseph County massage parlors.

The businesses and a South Bend home were searched as part of yesterday's 14-hour investigation involving police officers from all throughout Indiana.

Top Oriental Massage is one of the businesses in question and they actually opened and turned their light on before 4 this afternoon.

But their future is a bit uncertain as police say these places could close indefinitely depending on the investigation.

Human trafficking, sexual solicitation and tax fraud are suspected at Top Oriental Massage, Best Chinese Massage and The Relax Place-o in South Bend and Best Oriental Massage in Granger.

Sheriff William Bill Redman says they’ve been looking into these accusations for quite some time.

So far, police have seized thousands of pages of financial records and more than $88-thousand dollars in cash from the businesses and the owner's home on Buckhorn Drive in South Bend.

Reportedly, multiple women were living inside each of the massage parlors.

Investigators interviewed 9 customers, 12 employees who are also considered victim and the managers and owners.

Based on information they have so far, police can confirm that at least some of the women have been forced to work against their will.

Some of the victims also saying that sexual activity has occurred with the customers.

St. Joseph County is the lead agency but they're working with multiple agencies across Indiana including the Indiana State Police and I-R-S.

No arrests have been made right now.

But depending on the outcome of the investigation, there's potential for felony at the state and federal level, according to Sheriff Redman.

The two women who provided information are getting aide and help back to their home country.
