The NYPD has released surveillance video of a suspect they say is wanted for three separate robberies in the past two months in which he targeted teens entering their apartment buildings.

The first incident occurred on March 19 at about 1:15 p.m. near West 111th Street and Lenox Avenue when the suspect followed a 16-year-old boy into his apartment building’s elevator, police said. There the suspect threatened to shoot the victim if he did not give up his cellphone. The boy listened and the suspect fled on foot.

Two days later on March 21 at about 4 p.m. again near West 111th Street and Lenox Avenue, the suspect followed a 17-year-old boy into the elevator of his apartment building, according to cops. The suspect once again threatened to shoot the victim if he did not hand over his property. The boy listened and gave the man his cellphone, $10 and a MetroCard. The suspect then fled.
