PARAMUS - Police say social media helped to take down a North Jersey prostitution ring.     

Feng Qun Liu and Mei Zhi Zheng were arrested Wednesday night after police say they advertised prostitution from an apartment on North Fairview Avenue.

Police say during nearly three weeks of surveillance, they witnessed numerous men between the ages of 20 and 50 years old going in and out of the home.

Investigators believe the brothel had been open about two months, and they have no way to tell how many clients there were.
