A man is dead and another is critically injured in two separate stabbings that occurred in Waikiki early Tuesday, according to Honolulu police.

The first stabbing occurred in proximity to the Prince Jonah Kuhio Kalanianaole statue near the intersection of Kalakaua and Ohua avenues at about 12:40 a.m.

A man, described to be a visitor from California in his early 20s, and his friend were confronted by a group of individuals. A physical altercation ensued at which time an unknown suspect stabbed the victim in the upper torso, police said.

Emergency Medical Services personnel responded and pronounced the victim dead at the scene.

There are no arrests at this time.

Police have opened a second-degree murder investigation. CrimeStoppers Honolulu and police issued a bulletin seeking the public’s help in locating witnesses and identifying the suspect or suspects in the case.

Anyone with information is urged to call 955-8300. Anonymous tips may also be sent via honolulucrimestoppers.org or the P3 Tips app.

The victim was on vacation with a friend at the time of the deadly stabbing.

The Visitor Aloha Society of Hawaii, a non-profit organization, is assisting the victim’s family. “It’s such a tragic situation to have a family member come to Hawaii and get a phone call that your son or family member has been murdered. That’s a phone call nobody ever wants to receive,” said president and chief executive officer Jessica Lani Rich.

Shortly after the first stabbing, police and EMS responded to separate stabbing nearby in the vicinity of the Kapahulu Groin.

Police said a 29-year-old man was following a couple. The suspect then allegedly threatened the female and her boyfriend, 20, intervened.

Police said the suspect stabbed the boyfriend in the upper torso with a knife. He was taken in critical condition to a hospital.

The suspect and victims are not known to one another.

Police arrested the suspect at about 1:30 a.m. on suspicion of second-degree attempted murder and first-degree terroristic threatening.

Police are continuing their investigation in the stabbing cases.
