LEAGUE CITY, Texas (AP) — A recent prostitution investigation in Southeast Texas has led to the closure of six massage parlors in League City and nine arrests.

The Galveston County Daily News (http://bit.ly/1QuII7H ) reported Thursday that the businesses operated along Main Street and Marina Bay Drive.

Police Sgt. Stephen Antley says two massage businesses were not investigated for prostitution, but failed to be properly licensed by the state.

Antley says a special law enforcement unit started the investigation by targeting massage businesses amid concerns about possible regulation violations. Arrest affidavits say undercover officers entered some of the businesses and reported being offered sexual acts for $40.

The suspects face charges including prostitution or aggravated promotion of prostitution.
