BALLARD, Uintah County — Police are searching for four people after a man was beaten so badly outside a convenience store Wednesday that he had to be flown to Salt Lake City for treatment.

The man was assaulted about 5 p.m. outside a Maverik convenience store that sits on the Duchesne County-Uintah County line, said Roosevelt Police Chief Rick Harrison.

A gun was brandished during the incident, but no shots were fired, the chief said.

The victim, a 32-year-old Native American man, was hit in the head with an unknown object, the chief said. He was taken by ambulance to Uintah Basin Medical Center and then flown to a Salt Lake hospital.

Harrison declined to release the victim's name.

The man's attackers, who are also believed to be Native American, were gone when police arrived. But officers had stopped two vehicles as of 8:30 p.m. Wednesday and interviewed the people inside.

One of those traffic stops took place about 6 p.m. on Whiterocks Road. Roosevelt and Bureau of Indian Affairs police officers were seen handcuffing the occupants of a pickup truck. They interviewed and photographed some of them, then let them go.

Harrison said the occupants of a second vehicle were also briefly detained and interviewed, but no arrests were made.

Anyone with information about the assault is asked to call the Roosevelt Police Department at 435-722-2330.
