REXBURG — A fight between rival motorcycle group members at a charity ride for a boy battling cancer left two Pocatello men injured and gunshots fired, Rexburg police said.

    Nearly 400 motorcyclists gathered in Rexburg Saturday to grant 7-year-old Wesley Johnson's wish to ride a motorcycle. In the end, the young cancer patient got his wish, as well as more than $6,000 in donations to help pay his medical expenses. But the day did not end without a serious brawl between members of the Idaho Falls chapter of the Brother Speed motorcycle club and bikers with the Empties motorcycle group of Pocatello, police said.

    The 4 p.m. fight on 12th West left two Pocatello men, both members of the Empties, with injuries, according to police.

    One of those men, a 50-year-old, suffered minor injuries in the fight and eventually fired a 9 mm pistol in what he told police were warning shots in an attempt to break up the melee.  

    The other injured biker, a 57-year-old man, was discovered lying beside the road by police. He refused treatment at the scene but later drove himself to Madison Memorial Hospital, where he was treated for serious facial injuries and broken bones.

    As of Monday night, Rexburg police had not released the names of the men injured in the fight.

    Police said ongoing friction between the two motorcycle groups led to the brawl. The incident remains under investigation by Rexburg police.
