Mexican surveillance photos show Sean Penn was monitored before El Chapo meeting
After Hollywood actor Sean Penn accidentally led police to a wanted Mexican drug lord, a secret tunnel hidden behind a mirror helped Joaquin "El Chapo" Guzman flee - but only briefly.
Guzman was recaptured Friday, six months after breaking out of a Mexican prison.
New details about how police captured Guzman - including surveillance of Penn as he arrived in Mexico - have been revealed, as Mexican officials admit they face a long road ahead to extradite the drug boss to the United States.
Mexican newspaper El Universal has published 10 photographs that appear to show Penn and Mexican actress Kate Del Castillo arriving at an airport in October and greeting the men who apparently took them to a small airstrip, from which they flew to the jungle camp to meet Guzman.

Penn has admitted he feared he was being monitored as he flew to Mexico to meet Guzman, for an interview published by Rolling Stone this week.
The photos appear to have been taken with a telephoto lens from long distance. The newspaper said Monday they were part of a Mexican government intelligence file that it obtained.
Figures that closely resemble Penn and Del Castillo are seen wearing dark glasses, and in Penn's case, a baseball cap.
The newspaper says the intelligence file indicates that Mexican agents had been photographing Del Castillo since her first meeting with Guzman's lawyers in the city of Guadalajara, on June 16.
Guzman initially gave Mexican security officials the slip by opening a secret doorway hidden behind a mirror, and descending into a sophisticated tunnel leading to the city's drains.
He spent hours below ground as his henchmen sought to lure pursuing Marines up toward the roof of the house he had been holed up in. He eventually emerged from a manhole near a gas station 1.5 km across town as rains started to fill the drains and stole a car at gunpoint.
Video footage broadcast by Televisa on Monday showed Marines firing shots inside the property during the dawn raid in Los Mochis in Guzman's native state of Sinaloa, and images of the interior of the ground floor dressing room where the tunnel entrance was hidden.
The infamous boss of the Sinaloa drug cartel, Guzman was arrested on Friday after a months-long manhunt following his escape from a maximum security prison in July.
Marines found two women hiding in the bathroom of the house, along with DVDs of La Reina Del Sur, a fictional series about a female drug boss starring del Castillo.
"My holidays are over," Guzman said when he was finally caught, Televisa reported.
The US is seeking to have him extradited for the hundreds of tonnes of cocaine, methamphetamine and heroin he has exported across the border.
Mexico regularly extradites leading traffickers but the government of President Enrique Pena Nieto resisted handing over Guzman after his arrest in February 2014 as a point of national pride.
An official at the Mexican Attorney General's office told a local radio station on Monday that the extradition case will likely take "at least a year" to move forward.
Jose Manuel Merino told Radio Formula that the length of the process would depend on how hard the defendant's lawyers fight each stage. Merino said the process had lasted as long as six years, in one case.
The office issued a statement Sunday saying it had started the extradition mechanism by notifying Guzman that two arrest warrants from the US were being processed.
