New cartels show up in Mexico's list of top 69 traffickers arrested or killed

Mexican prosecutors have revealed the names of 69 top drug traffickers killed or arrested over the past year from a total list of 122 most-wanted drug capos drawn up at the start of President Enrique Pena Nieto's term.

The names provided to The Associated Press under a freedom of information request show the hyper-violent Zetas cartel was the most targeted gang, with 23 leaders arrested and four killed.

The list also sheds light on the emergence of several little-known drug gangs, such as the so-called Western Cartel.

The best-known name on the list is Zeta's leader Miguel Trevino Morales, who was arrested in July.

Prosecutors refused to identify the 53 remaining capos still at large, arguing they don't want to tip off the suspects.
