A woman was robbed in Waikiki early Sunday, but police caught the suspect just a few minutes later. The 26-year-old victim was pushed by a 20-year-old man, who then took her property just before 2:30 a.m. The suspect ran and the woman flagged down a police officer and pointed the suspect out.  He was arrested nearby on suspicion of second-degree robbery at 2:45 a.m.
