Police are searching for three men who robbed a Sunset Park spa at knifepoint early Sunday. The robbery happened around 3:22 a.m. inside the business at 772 57th St., according to the NYPD. Investigators say the individuals walked in with knives and ordered multiple people to lie on the floor. They say the attackers then punched and kicked the victims before stealing their property and taking cash from the register. Police say the group ran off. It’s unclear how much money was taken and how many people were inside at the time. No injuries were reported. The spa is listed online as a 24-hour business. Police released photos of two of the men they believe were involved and are asking for the public’s help identifying them. Anyone with information is urged to contact Crime Stoppers.
