Honolulu police arrested a 34-year-old man after he snatched a gold necklace from a 50-year-old man in the Ala Moana area Monday.
Police said the suspect walked up to the victim on the sidewalk on Kapiolani Boulevard at about 1:50 p.m. and used physical force to take the necklace.
The suspect fled the scene.
Responding patrol officers located him about a half-hour later in the area of Poni and Makaloa streets and arrested him on suspicion of second-degree robbery and criminal contempt of court.
Police said the suspect and victim are not known to one another.
