A member of a Utah white supremacist gang was charged on Friday for allegedly kidnapping, tying up and forcibly tattooing a woman almost three years ago.

According to a probable cause statement filed by the Salt Lake County District Attorney's Office, Robert James Calder, 39, and six other members of the Silent Aryan Warriors gang met with a woman at the Mountain Shadows Apartments, 3825 S. 700 West, on Nov. 1, 2010.

During the meeting, Calder allegedly accused the woman of being an undercover FBI agent and pointed a gun at her face.

Prosecutors say Calder then tied the woman up by her ankles and wrists and gagged her with a sock, held in place with duct tape wrapped around her head.

He then told the woman he was going to "finish her tattoos," and used a tattoo gun to ink "RATTA 100%" across her stomach, prosecutors say.

Afterward, the woman was allegedly held captive for about eight hours, as Calder and others allegedly beat her until she passed out.

The woman was only able to name Calder, who goes by the moniker "Stinger," as one of her assailants. Another gang member, who was only identified as "Youngster," also was with the group, court documents state.

Calder was charged in 3rd District Court with aggravated kidnapping, a first-degree felony, and aggravated assault, a second-degree felony. Prosecutors wrote in their filing that Calder is subject to enhanced gang- and weapons-related penalties.

Calder was arrested Friday and was held at the Salt Lake County Jail on a $100,000 bond.
