More than 40 Salt Lake police officers surrounded a Central City residence Tuesday morning and took a man believed to be a Vietnamese gang member into custody after he arrived at his parents' home with a gun.

At press time, the suspect was being held at the house. Three other people - as of yet unidentified - were still in the house.Vuong Nguyen, 18, reached the home at 310 E. 800 South about 9 a.m. and hid a handgun behind the house. The parents called police, and officers and SWAT teams arrived on the scene shortly after.

Police were cautious about approaching the home because of safety concerns for Nguyen's younger brothers, one of whom was home sleeping at the time Nguyen arrived. The younger brother later left the home safely.

Police Lt. Jim Bell said Nguyen's parents reported that he had threatened to kill his younger brothers when they returned home from school on Tuesday.

By 11 a.m., 25 police cars were parked in the Zaccheo's Restaurant parking lot, 280 E. 800 South. Authorities disconnected the incoming phone line into the home so only they could communicate with Nguyen, and a Vietnamese interpreter was helping with communications.

Several other Vietnamese interpreters told police they were too afraid of Nguyen to help, Bell said.

Nguyen, who was thought to be living in California, is a suspect in the Monday afternoon shooting of his cousin, Dung Nguyen, 19. Dung Nguyen was shot in the upper right arm with a .22-caliber gun at the same house and was treated for the wound.

Vuong Nguyen is thought to be a member of a Los Angeles-based Vietnamese gang and is wanted for questioning in connection with a homicide that occurred in Salt Lake City about a year ago, Bell said.

The Monday incident occurred about 6 p.m., but the assailant escaped before police arrived, said Salt Lake Police Lt. Joel Campbell. "The victim and the suspect were having some kind of an argument when the suspect shot him and then ran off."

Because the victim didn't speak English, police were unable to determine what caused the altercation.
