A reputed white supremacist accused of shooting two Canyon County sheriff's deputies has been arrested on a federal gun charge.

Kyle Alan Batt, 27, of Caldwell, was booked into the Ada County Jail after being taken into custody about 10 a.m. Friday at the Boise medical center where he'd just completed physical rehabilitation.

A complaint unsealed Friday in U.S. District Court in Boise accuses Batt of being a felon in possession of a firearm for the gun he had with him after officers found him hiding in a garage in Caldwell early Oct. 24, hours after he's accused of shooting deputies Brad Childers and Mike Roth.

Batt has not yet been charged with shooting the deputies; Canyon County prosecutors are awaiting the conclusions of a Nampa Police Department investigation. But a federal judge found probable cause for the gun charge at the request of the Bureau of Alcohol, Firearms and Tobacco.

Christopher Atwood, a special assistant U.S. attorney hired to address gang crimes, is prosecuting the case. Atwood declined to comment, but the Anti-Defamation League has identified Batt as a white supremacist with ties to local hate groups, including the Hammerskin Nation. But Batt's older brother, Ryan Batt, said his brother doesn't belong to any groups and has long regretted the "white power" tattoo he got on his chest in prison several years ago.

Kyle Batt has a felony conviction from 2004 for possession of a controlled substance, which prohibits him from possessing firearms. He faces up to 10 years in prison and three years of probation if convicted of the federal gun charge. His preliminary hearing is set for Dec. 3 at the federal courthouse in Boise.

Childers and Roth were among five deputies looking for Batt at his father's home in the 24000 block of Sheryl Lane in Caldwell on the night of the shooting. Police say they wanted to arrest him for aggravated assault after a fight involving the mother of his daughter earlier that day. Police say Batt opened fire and escaped.

Childers, a K-9 handler and SWAT team member, was treated and released from a hospital that day and has returned to patrol. Roth was shot twice in one arm and is recovering at home.

Childers returned fire, striking Batt at least once in a leg, police say. Batt fired shots into Roth's chest as he ran by, police say, but a bullet-proof vest saved the deputy's life.

Police say Batt shot himself in the face when police found him in a nearby garage hours later, but Ryan Batt said the bullet doesn't appear to have damaged his brother's brain.

The Anti-Defamation League describes the shootings as the lat­est in a string of nearly 30 between police and domes­tic extrem­ists in the United States since 2009. Ryan Batt told the Statesman his brother does not hate government officials and was simply drunk on whiskey and distraught about the fight with his ex-girlfriend when the deputies approached.

Childers and Roth were honored with footballs autographed by Boise State Coach Chris Petersen last Saturday.
