Police arrested the suspect on suspicion of second-degree attempted murder, but released him just before midnight while the investigation continues.

The incident occurred at 5:30 p.m. at Kaunala Beach near Haleiwa.

Police said the two males were surfing when they got into a fight. During the fight, the suspect allegedly held the victim underwater.
