WICHITA, Kan. (AP) — Police have asked Wichita officials to consider regulating massage businesses in hopes of reducing human trafficking.

It is unclear how many massage businesses actually operate in Wichita or the state, because they are unregulated and don’t require licensing. But Wichita police say they’ve had complaints since 2013 of some massage businesses that sell sexual acts and that some of these businesses are engaged in human trafficking.

The Wichita Eagle reports that Deputy Chief Hassan Ramzah says the move is aimed at keeping the community safe.

But Charles O’Hara, a lawyer who has represented clients charged with human trafficking, said police are using the regulation as an excuse to try to outlaw those businesses.
