A 21-year-old woman has been arrested on suspicion of robbing a Japanese tourist on Waikiki Beach, police said Tuesday.

The woman allegedly pointed a gun at the 38-year-old Yokohama man outside his Waikiki hotel room early Monday morning, tying him up and stealing his belongings with two male accomplices, they said.

The three left, but the woman was held by a guard at the hotel and handed over to police.

Before the stickup, she had asked the victim for his room number and phone number, police said without elaborating. The man sustained minor injuries in the attack, they added.
