Salt Lake City police Detective Josh Ashdown said a pair of Utah Jazz fans were attending the basketball game Wednesday night when they started trash talking with a pair of Lakers fans.
The discussion escalated and the Lakers fans challenged the Jazz fans to a fight, which they declined, Ashdown said.
Security threw the two Lakers' fans out of the game, but they apparently decided to stick around to continue the confrontation with the Jazz fans, he said.
The Lakers' fans spotted the Jazz fans standing on the corner of 100 South and 400 West and started trash talking again.
At that point, one of the Lakers' fans pulled out pepper spray fogger and let loose with it, police said.
