Police are asking Upper East Siders to be on the lookout for a knife-wielding mugger suspected in a string of robberies in the neighborhood over the past week. The first is believed to have occurred at 12:45 a.m. on September 4th, when the perp—described as a mustachioed black male, between the ages of 35 and 40, about 5-foot-10 and 190 pounds—relieved a 32-year-old man of his wallet and cellphone.
