LAS VEGAS (AP) _ An Atlanta-bound Delta Airlines flight made an unscheduled stop in Las Vegas early Saturday after a passenger scuffled with the flight crew, officials said.

Four people suffered minor injuries, including a baby scalded by spilled coffee.

Hung Cong Duong, 30, a Tampa, Fla., resident originally from Vietnam, was charged with interfering with a flight crew, and FBI spokesman Kevin Caudle said he could face more charges, including assault.

The man's brother told FBI agents his brother became unruly because he hadn't taken his medication, but Caudle didn't know what kind of medication he referred to.

``The individual who had the altercation was up and moving around when he wasn't supposed to be and they tried to seat him. He tried to get past the beverage cart and just got violent,'' McCarran International Airport spokesman John Hanks said.

Among the injured on Delta Flight 194, which originated in Los Angeles, was a 17-month-old boy burned by spilled coffee. He was treated at University Medical Center and released. Also injured were a flight attendant and two female passengers. They were treated at the scene for cuts and bruises.

A Delta spokesperson did not immediately return a phone call from The Associated Press seeking comment.
