Des Moines, Iowa television station KCCI reports that Mickael Gordon Thomson — the musician better known as Mick Thomson of SLIPKNOT — and his brother Andrew were injured in an early Wednesday morning (March 11) knife fight in the guitarist's front yard.
According to a police news release, the altercation started inside Mickael's home in Clive, Iowa and spilled into the front yard about 4:25 a.m., where it became physical.
When officers arrived, the two men appeared to be intoxicated and sustained serious, non-life-threatening injuries, with the 41-year-old Mickael suffering a stab wound to the back of his head.
Mickael and his 35-year-old brother were transported to local hospitals in separate ambulances but no charges had been filed at press time.
Andrew Thomson's Iowa criminal record includes a 2012 arrest for public intoxication in Polk County, court records show.
SLIPKNOT just finished perfoming at Australia's Soundwave festival in support of the band's new album, ".5: The Gray Chapter", which came out in October 2014 and topped the Billboard album chart.
SLIPKNOT recently released a live video for the song "Custer", shot at 2014's Knotfest in Devore, California.
SLIPKNOT took six years to make its latest album, and that time was filled with tragedy and turmoil. In a recent interview with Music Radar, Mick Thomson said that with the band members being able to write music on the road on their laptops, there should be less time between records from now on. He explained: "It enables us to have songs in the can already before we go in a studio to work on a new album. We hope to do our next record sooner after touring '.5'. We don't want to spend the same amount of time between albums as we've done with the last two."
