The NYPD is looking for a suspect in connection with five robberies, mostly involving iPhone theft, in the subway system.      

Police say the first robbery occurred May 25 on a southbound No. 3 train. The suspect and an accomplice robbed a rider of his iPhone after threatening to shoot him.      

Three other robberies were committed in June, two on one day. The last robbery occurred July 2 inside the 145th Street and Lenox Avenue. The victim was robbed of an undermined amount of cash. In all but the last incident, iPhones were stolen.      

Police say the suspect is in his early 20s with brown eyes and a slender build. He's believed to be about 6 feet tall and was last seen wearing a Yankee baseball hat, gray hooded sweatshirt and jeans.      

His alleged accomplice, Bruce Williams, was arrested July 3 on charges of robbery and criminal possession of stolen property. Information about his lawyer wasn't available.
