HILO — Hawaii County police say a man and woman were robbed early Tuesday morning and the man beaten with what might have been a baseball bat.

The incident took place on Kapiolani Street below the University of Hawaii-Hilo campus between 12:30 a.m. and 1 a.m.
Police say the man, 21, and woman, 20, were walking when they were confronted by three males who demanded money.
The male victim was struck by an object, possibly a baseball bat, and knocked to the ground. One of the assailants bent over him and cut the straps of his backpack to remove it.
Another one demanded money from the woman. She handed him an undisclosed amount of cash.
