An off-duty Customs and Border Patrol agent was shot in New York City's Riverside Park late Saturday in an alleged robbery that did not appear to target him because of his job, police said.

Miguel Mora, 21, is being investigated as a person of interest in the attempted robbery and shooting, New York Police Commissioner Jessica Tisch said at a news conference Sunday. He was hospitalized with gunshot wounds investigators believe he sustained during the incident but was expected to be arrested later Sunday, Tisch said.
