The guy is a scumbag but to bring in Police i doubt they would do anything but may open up more issues especially with PCD. Are they legal operating in private homes, are the girls on a permanent or, working visa or here on holiday? PCD maybe in more trouble than the guy..
That said, Management may need to hire a bouncer for each private location if they want to keep the girls safe.
My PCD experience the girls are usually working alone or another working roommate different room. Mamasan working at a different location so they dont know what offenders even look like...
Most of the time it works well but theres always gonna be a dickhead that would ruin it..
