 The Tijuana Cartel, also known as the Arellano Félix Organization, was once among Mexico's most powerful.It is based in Tijuana, one of the most strategically important border towns in Mexico, and continues to export drugs even after being weakened by an internal war in 2009.Due to infighting, arrests and the deaths of some of its top members, the Tijuana Cartel is a fraction of what it was in the 1990s and early 2000s, when it was considered one of the most potent and violent criminal organizations in Mexico by the police.
