"I was driving my boat south in Bayou Camp Town and a man in a camp on the west side of the bayou was aiming a long gun at our boat," Klein wrote in a voluntary statement to the Plaquemines Parish Sheriff's Office. "As we passed by, he shot over my boat."
Klein, 45, of Weatherford, Texas, told reporters at the New Orleans Arena before Sunday's final Classic weigh-in that ESPN cameramen filming the tournament captured the incident.
"It's an isolated incident," said Klein, who is fishing his 21st Classic. "It's the first time in my career that I've ever had that happen, and I have never heard of anyone else ever having that happen."
Klein plans to press charges if the shooter is caught. "He needs to be taken care of," Klein said.
Klein said it appeared the man intentionally shot over the boat from about 70 yards away at about 11 a.m. with what he thought was a shotgun.
"We're delighted that Gary Klein is safe and sound," said BASS spokesman George McNeilly. "I've never heard of anything of this nature happening before on the Bass Tour.
"Gary Klein filed a voluntary incident report with the sheriff's department, and the authorities are investigating."
