Honolulu police are investigating two robberies of two homeless men in the downtown Honolulu and Chinatown areas over the weekend.

Police said three male suspects robbed a 60-year-old homeless man at gunpoint on Alakea Street at about 4:10 a.m. Saturday.

The perpetrators also allegedly shot the victim with a slingshot when the victim fought with them, resulting in a minor undisclosed injury.

Police said the suspects fled on foot with the man’s bag.

About five minutes later, a second robbery occurred nearby on Vineyard Boulevard involving a 53-year-old homeless man. Police said a male suspect robbed the victim of his cellphone and fled.

The robberies are possibly related.

There are no arrests at this time.
