Here we go again, folks: LAX Evacuated After Gunman Fires at TSA Agent.

(CNN) — A suspect has been shot and is in police custody after Friday’s shooting at Los Angeles International Airport, a law enforcement source close to the investigation tells CNN’s Miguel Marquez.

A person with a firearm at Los Angeles International Airport approached a checkpoint at Terminal 3 and opened fire Friday morning at a Transportation Security Administration agent, a former Los Angeles Police Department ranking officer who was at the scene told CNN.

Reports of gunfire Friday morning at Los Angeles International Airport prompted evacuations of portions of LAX and led to a “ground stop” for arriving planes, said police and the Federal Aviation Administration.

No further details were immediately available on the gunfire, police said.

Airport officials said a police incident began about 9:30 a.m. at Terminal 3 at LAX, airport spokeswoman Nancy Suey Castles said.

UPDATE: One TSA employee killed, one wounded in LAX shooting
