Honolulu Police Lt. Bill Kato, who heads the department's homicide detail, said investigators today will be interviewing a number of witnesses.

Kato said the stabbing happened near a crowded bus stop in front of the Longs Drug store on Hotel Street and detectives were receiving calls today from bus riders who noticed a commotion but who went home without talking to police yesterday.

"Now that they are returning to work (today), they are calling us to report what they saw," Kato said.

Witnesses yesterday told police two men were involved in some type of scuffle before one of them pulled a knife and stabbed the other.

The injured man was taken to The Queen's Medical Center, where he was pronounced dead a short time later.

Police said the assailant, described as middle-aged, was last seen walking away from the scene with a woman.

Sunglasses incident ends in robbery arrest

Two men, ages 21 and 43, were arrested yesterday on suspicion of second-degree robbery after they allegedly began shoving a store security guard who was confronting them about taking a pair of sunglasses from the store where she works.
