Pictures inside the cell of Joaquin 'El Chapo' Guzman show the 50cm-by-50cm grill in the shower floor.

Guzman entered the hole Saturday night and climbed down a 32ft shaft into a complex tunnel system.

Mexican officials estimate it had taken his henchmen a total of 352 days to craft the escape route.

The bathroom was a blind spot for security cameras trained on his cell, which filmed the moment he disappeared.  Experts say he would have paid an estimated $50million in bribes to a group of guards in order to get out. 

This is the 50cm-by-50cm hole at the base of El Chapo's shower that he used to enter an elaborate series of escape tunnels.

This photo shows the shower area where authorities claim drug lord Joaquin 'El Chapo' Guzman, slipped into a tunnel to escape from his prison cell at the Altiplano maximum security prison, in Almoloya, west of Mexico City.

Mexican authorities have distributed 100,000 photographs of drug lord Joaquin 'El Chapo' Guzman to highway toll booths since his weekend escape from a maximum security prison.

The entrance was in a place beyond the view of security cameras at Mexico's toughest prison. They also said it was clear the escape by Mexico's most powerful drug lord must have involved inside help on a grand scale.

Experts have said the tunnel would have been more than a year in planning and building. The digging would have caused noise.

A view of the opening of the tunnel shows a ladder heading out of the shaft into the warehouse that the drug lord used to escape.

The tunnel is thought to have taken a year to construct, with four men.

This photo provided by Mexico's attorney general, shows the exit of the tunnel they claim was used by the drug lord after he got away from the prison.

Areas of the mile-long tunnel Guzman used to escape are filled with buckets, metal piping and what appears to be insulation.

At the end of the tunnel Guzman appears to have used to escape, he had to have climbed out into a building a mile away.

Judicial workers and a forensic team were seen at the warehouse on Tuesday as they investigated Guzman's escape.

Officers search for clues near the prison on Tuesday, just three days after drugs lord Guzman got away.

Henchmen working for El Chapo spent a year digging a tunnel, leading from the inside of the Altiplano prison showers to the Santa Juana construction site nearly a mile away.

The tunnel was a miracle of underground engineering, and came complete with ventilation, electric lights and a motorbike fitted to rails, to help remove the massive amounts of earth and on which El Chapo could make his getaway.

Authorities look into the entrance to a secret tunnel through which Guzman is believed to had fled. He used the tunnel to travel the 0.9miles between the prison and the Santa Juana construction site. Once there, he was able to take his time, using the bathroom and collecting a change of clothes, before disappearing once again.

Pictured is the interior of the home through which Guzman fled. Clothes and a phone charger could be seen inside.

A half-constructed house concealed the site where El Chapo's henchmen began digging the tunnel a year ago.

The Altiplano Federal Penitentiary complex in Almoloya de Juarez, is just 50 miles outside of the nation's capital Mexico City.
