A Brooklyn nail salon employee was busted after being caught on camera hammering a customer with a stick in a wild viral Facebook video, police said Sunday. Huiyue Zheng, 32, was charged with assault and weapon possession. She was freed on personal recognizance after a hearing Saturday in Brooklyn Criminal Court. Also arrested was a customer, Christina Thomas â€” the woman Zheng is accused of striking — on misdemeanor assault and other charges. Thomas is accused of punching, slapping and dragging a 35-year-old woman in the salon. She was also released on her own recognizance. The viral video â€” which went up Friday and by Sunday night had more than 650,000 views â€” was shot at the New Red Apple Nails salon on Nostrand Ave. near Martense St. in East Flatbush. It shows salon workers surrounding a woman. One of the workers then starts whacking at the woman with a blue broomstick. As the woman flees the business, a second customer yells out: â€œWhat are you doing!â€ The woman with the stick hit that customer as well.
