DENVER – One person died and seven others were injured in a shooting and stabbing at a motorcycle expo Saturday, Denver police said.

Police spokeswoman Raquel Lopez says the incident occurred about 1 p.m. Saturday at the National Western Complex. The Colorado Motorcycle Expo is being held this weekend at the complex.

Police Chief Robert White said one person was fatally shot and seven others were wounded when a fight broke out a motorcycle expo on Saturday.

He told reporters it was unclear what prompted the incident. He said other events associated with the expo have been canceled.

White said investigators believe there was an exchange of gunfire. In addition to the person who was shot and killed, three others were shot. White said another person was stabbed and three others suffered injuries from a fistfight.

Lopez said she couldn’t say whether the incident was gang related. She said police are still investigating and no arrests have been made.

Bob Cook told the Denver Post the shooting happened near his leather goods company booth.

Cook said he heard two shots fired and saw people dive under tables. He said he didn’t hear any arguments before the shooting and didn’t know what prompted it.
