MEXICO CITY (AP) -- Mexico's federal police have replaced all 348 officers assigned to security details at the Mexico City International Airport in the wake of the June 25 shooting deaths of three federal policemen killed by fellow officers believed to be involved in trafficking drugs through the terminal.

Federal Police regional security chief Luis Cardenas Palomino said the police agents have been reassigned to different states. They have been replaced by federal police who have passed double vetting and background checks.

One of the three officers sought in the shooting has been captured. Two others are still at large.

Cardenas Palomino said Sunday there is a reward of 3.4 million pesos, or $259,000, for information leading to their arrest.

The rogue officers were allegedly part of a trafficking ring that flew in cocaine from Peru.
