Based on this information, the search for the world's most wanted drug lord has focused in recent weeks on a rugged area that stretches from Sinaloa into neighbouring Durango state, part of Mexico's famed Golden Triangle drug-producing region that is considered Guzman's home turf, said the official, who spoke on condition of anonymity because the investigation is underway.

After Guzman'sescape from the maximum-security prison where he was being held not far from Mexico City, the official said the drug lordwas taken to the central state of Queretaro. From there, he was flown in a small plane to the Sinaloan mountains, the official said.

Pilot captured

Several days ago, Mexican Attorney General Arely Gomez told Congress that authorities had captured a man who had aided Guzman after his escape. On Saturday, the federal official saidthe man was the pilot who flew the escaped drug trafficker in the light plane.

Late Friday, Mexico's government said Guzman had avoided capture in an operation in the mountains of northwestern Mexico.

A statement by Mexico's security cabinet said officials think Guzman injured a leg and his face fleeing Mexican marines in the rugged terrain. It provided no details on when or exactly where the operation took place, but the area of mountains of Sinaloa and Durango is in northwest Mexico.

The statement cited information-sharing with international agencies for leading authorities to the area.

Guzman previously escaped from another maximum-security prison in 2001, and evaded capture for years in the mountains of Sinaloa.

His most recent escape strained relations with the United States, which had formally requested the drug kingpin's extradition just weeks earlier.

Blind spot

A variety of U.S. officials, including lawmakers and law enforcement officials, had called for Guzman's transfer to the U.S. since his arrest in February 2014. However, Mexican officials decided Guzman wouldn't be sent to the U.S. until he had served time for all of his crimes in Mexico.

Guzman escaped through a sophisticated 1.6-kilometre tunnel that opened in the floor of his cell's shower. A surveillance video of Guzman's cell shows him walking to the shower where there was a blind spot in the security camera's view crouching down and then vanishing.

Mexico has issued arrest warrants for 23 former officials, guards or police officers accused of participating in his escape. In addition, 10 civilians are being held under a form of house arrest.
