Argentina's top security official says the government is acting on a tip that fugitive Mexican drug boss Joaquin "El Chapo" Guzman could be in the South American nation.

Security Minister Sergio Berni says authorities "received information that 'El Chapo' tried to cross the Chilean-Argentine border."

Berni said Friday that extra federal agents were being sent to the border while the information was being analyzed. He did not elaborate on the source or nature of the tip.

Nor did he specify where along the long border, which includes the Andes mountain range and large swaths of thick Patagonian forest, other than to say it was in the "southern" part of the country.

Guzman is head of Mexico's Sinaloa cartel. He has twice escaped maximum-security prisons, most recently in July.
