One incident happened on the Lower East Side, while the other occurred in Washington Heights.
Both suspects are described as Hispanic or black males, 25 to 35 years old. No property was removed in either incident.
Anyone with information regarding these incidents is asked to call Crime Stoppers at 1-800-577-TIPS (8477).
