The NYPD reported the bandit was armed with a kitchen knife when he approached the 22-year-old female victim as she entered her Evergreen Avenue building on Thursday just after midnight. The NYPD said  he forced the woman to the fourth-floor landing of her apartment building, where he assaulted her and took the pocketbook.

The suspect fled the building, and the victim was treated at a hospital.

Police say the suspect is between 5-foot-11 and 6-foot-2 and weighs 180 to 190 pounds. He is believed to be in his mid- to late 20s.
