Kyrie Irving was the target of another idiot fan Sunday night who almost beaned the b-baller in the head with a water bottle ... and this time the culprit was arrested.
The incident went down in Boston at TD Gardens ... as Kylie was walking out, you see the bottle come within a hair's breadth of his head. His teammates were outraged, and Tyler Johnson scoped out the crowd and ID'd the culprit.
