Police said they intend to file charges and have asked witnesses to come forward.
Salt Lake City, like many other cities across America has seen many people protest after the death of a black man, George Floyd, in police custody.
On Sunday, fires burned near the White House, stores were looted in New York City and Southern California, and a tanker truck drove into marchers in Minneapolis as the United States struggled to contain chaotic protests over race and policing.
National Guard troops were deployed in 15 states and Washington, DC in an attempt to quell a sixth night of violence on Sunday.
Floyd’s death caused outrage after video footage showed a white Minneapolis police officer kneeling on the neck of the 46-year-old’s neck for nearly nine minutes before he died on May 25.
Authorities imposed curfews on dozens of cities across the US. President Donald Trump described the protesters as “thugs”.
