KCBS, reporting live on the shootout with fugitive former Los Angeles police officer Christopher Dorner, was pranked by a man claiming to be a U.S. Fish and Game Commission official.
The man, who called in to the television station and identified himself as "Mike Taugher," said he was an official confirming that an officer from the department had first seen Dorner, the alleged killer of three people who has sparked a massive manhunt through Southern California.
The caller said that Ronnie the Limo Driver, radio show host Howard Stern's head of security, was caught in a gunfire fight with Dorner.
"We believe it was Ronnie the Limo Driver firing at Mr. Dorner and we believe that he hit him," the caller said.
As the reporter continued interviewing the bogus fish and game official, the man interrupted her with a vulgarity.
"You're a real dumbass," the man said on air. "You still don't know that this is a prank?"
The line immediately went dead as the reporter scrambled to excuse the mistake.
"Someone's taking advantage of live television during a very serious day in Los Angeles," the reporter said on air, as B-roll of Big Bear played on the screen.
A gunman remained holed up in a cabin about 30 minutes outside Big Bear.
