The younger man first told police he got into an argument with the older man, who was aboard a boat tied to a pier, when the older man took out a gun and fired it into the air.

Officers went to the scene and arrested the older man about 1:40 a.m. on suspicion of first-degree terroristic threatening. But the younger man later recanted the part about a shot being fired into the air and said the man who was arrested took out a knife but did not move toward him with it, police said.

Police downgraded the case to suspicion of second-degree terroristic threatening.
