One person was killed in an explosion near a packed football stadium at the University of Oklahoma (search) on Saturday night in what authorities said appeared to be a suicide.
The blast, in a traffic circle about 100 yards from Oklahoma Memorial Stadium (search), could be heard by some in the crowd of 84,000, but university President David Boren (search) said no one inside the stadium was ever in danger.
"We are apparently dealing with an individual suicide, which is under full investigation," Boren said in a statement. There was no information about the person who was killed, and no reports of any other injuries.
A police bomb squad detonated explosives found at the site of the blast. The area near the stadium was searched by bomb-sniffing dogs.
Jaclyn Hull, an OU freshman who left the game shortly before the explosion, said she saw "a little bit of smoke, about as much as you would see coming up from a grill."
Officers cordoned off an area west of the stadium after the explosion and nobody was allowed out of the stadium for about a half-hour after the blast, which occurred shortly before 8 p.m., about halftime of the Sooners' game against Kansas State (search). The game continued.
