It is too early to know if the apprehension of one of the world's most powerful drug lords will have an effect in the drug flow into Southern Arizona, U.S. Drug Enforcement Agency officials said.

Joaquin Guzman, known as El Chapo and head of the influential Sinaloa cartel, was arrested this weekend in the Mexican state of Sinaloa.

He is considered by authorities to be the most important leader of an illegal drug organization since the notorious Colombian trafficker Pablo Escobar.

DEA officials said the arrest was made possible though a collaboration of Mexican and U.S. agencies.

Large seizures of illegal substances at the border may slow down for the near future, officials added.
