A man was seriously injured after an assailant sliced three of his fingers off and cut him in the chest with a machete Friday.

The two men apparently got into a fight sparked by road rage 10 miles up the canyon about 3:30 p.m. The man with the machete was parked on the road, which irritated the victim who was trying to pass, Salt Lake County Deputy Sheriff Craig Carroll said.The two got into an argument and a fight.

"The suspect apparently lost the fight, so he came back with a machete," Carroll said. "The victim put his hand up to stop the blade and had three fingers cut off before it cut his chest."

Paramedics flew the victim by helicopter to University Hospital, where he was in serious condition later Friday, Carroll said. Deputies didn't release his name, and Carroll didn't know his age or address.

After the assault, a friend of the victim drove him to the Millcreek Inn restaurant. The friend, who suffered minor cuts from the machete, called for help.

The assailant, driving a green car, apparently sped out of the canyon. Lt. Mike Wardle said an uninjured friend from the victim's vehicle was being driven home by a deputy when he spotted the alleged assailant and a companion by the side of the road at about 1200 West and 3900 South.

Wardle said the two were being questioned late Friday.
