A reputed Caldwell gang member already facing seven years in federal prison has been sentenced for assaulting an inmate at the Canyon County Jail.

Baldemar Arteaga Jr., 28, will serve his 5-year sentence for aggravated assault the same time as the federal sentence imposed Sept. 17 in U.S. District Court in Boise for being a felon in possession of a firearm. In that case, Arteaga sold two shotguns to a confidential informant during a meeting at a home in Caldwell in February 2011, according to federal court documents.

Arteaga has a felony drug conviction from 2005 in Minidoka County that prohibits him from possessing firearms. He was in jail on the federal charge and on a drug charge when he and five other gang members, Gabriel Torres, Damian Sanchez, Fernando Saldana, Adrian Contreras and Roberto Rojas, beat and punched the man Feb. 15 in an attack that was captured on jail surveillance video, according to an earlier Canyon County news release.

Arteaga is the last of the six to be sentenced, which occurred Wednesday before 3rd District Judge Juneal Kerrick. His charge was reduced from felony rioting in jail, which carries a maximum penalty of 25 years in prison.
