One teenager is dead and two others were in critical condition Friday night after suffering full cardiac arrests at the Salt Palace during a concert by the rock band AC/DC.

The youth who died apparently suffered cardiac arrest and was transported to the University of Utah Medical Center, where he was pronounced dead, nursing supervisor Pam Bennett said.Two other teenagers - a male and a female - were taken to Holy Cross Hospital where they were listed in critical condition, a hospital official said.

Neither the names of the victims nor the circumstances surrounding the incidents were available late Friday.

In addition, two other youths were injured at the concert. A female teenager was taken to LDS Hospital after being trampled close to the stage, according to a Salt Lake Fire Department official. One youth reportedly suffered head injuries when he fell 20 feet from the second floor of the Salt Palace into a fountain at the southeast corner of the concourse.
