A heartless thief robbed at least three Manhattan cancer patients during their treatments, law-enforcement sources said.
Arthur Johnson, a 43-year-old homeless man, was busted in three robberies and is suspected in three other cases.
Johnson allegedly robbed a 60-year-old Queens man at the office of East River Medical Imaging at 519 E. 72nd St. on Nov. 8.
Nine days later, he robbed a 76-year-old patient at Memorial Sloan-Kettering Cancer Center, and he swiped the wallet of a 30-year-old West Side resident at Sloan-Kettering on Nov. 23, according to the sources.
