DENVER (AP) — One person died and six 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.

Dr. Kevin McVaney of Denver Health Medical Center said six people were admitted to the hospital. Three were in critical condition and three were stable, he said.

McVaney did not release details about what injuries they were being treated for.

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 (http://dpo.st/1SsnPvS ) that 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 doesn't know what prompted it.

A posting on the Colorado Motorcycle Expo Facebook page said the event was going on as scheduled Sunday.

"Rest assured that all of the offending parties have been ejected and all is well," the posting said.
