The Tijuana Cartel, also known as the Arellano Félix Organization, is a criminal group based in Tijuana, Mexico. It was founded in the late 1980s and became prominent in drug trafficking, particularly in smuggling cocaine and marijuana into the United States. The cartel is known for its violent tactics and conflicts with rival groups, including the Sinaloa Cartel. The cartel was led by the Arellano Félix brothers, who played a significant role in its operations. Over the years, law enforcement efforts have targeted the cartel, leading to the arrest and death of key members. Despite these challenges, the Tijuana Cartel remains active in the drug trade and continues to influence organized crime in the region.
