(CNN) -- Rodeo officials in Canada are examining safety procedures after a bull bucked its rider, jumped a steel security barrier and bolted into a crowd of spectators.
One woman was hospitalized after a runaway bull named Rewind trampled her at the Canadian Finals Rodeo in Edmonton, Alberta, Friday. Three others were injured and treated by paramedics at the event, according to a statement released by the Northlands Organization, which sponsored the event.
Video from CNN affiliate CTV shows a chaotic scene as spectators frantically scattered away from the bull. One woman gripped tightly to the security railing. An onlooker lifted a child out of her seat to protect her from the approaching animal.
"Well, we have us an issue here now," an announcer said. "I suggest you get high [in the stands] really fast."
Gary Rempel, the man responsible for roping animals and taking them off the field, told reporters it was the first time he had ever seen a bull jump into the crowd in an indoor arena. Organizers said it was the first time in the event's history that something like that had occurred.
"I'm glad I caught him. That's all I can say," Rempel said.
Canadian Finals Rodeo Commissioner John Windwick told CTV that officials were reviewing safety procedures after the incident.
"We're going to look into adding additional steel or pulling back from seats, all of the above. We've taken a look at it immediately. This is a rare occurrence, but we're going to address it and make sure that our fans are safe," he said.
Rewind will not compete any more this year, CTV reported, but organizers told the CNN affiliate that that the bull's career was not over.
