Four more officials were charged after their suspected involvement in the escape of Mexican drug lord Joaquin “El Chapo” Guzman. The number of officials charged in the jailbreak is now seven.

Two of the charged officials were members of Mexico’s intelligence agency, CISEN, while the other two were prison guards assigned to video monitor the drug lord’s cell.

The four security workers were believed to have not followed certain “protocols and norms.” Moreover, they failed to report the notorious drug lord’s jailbreak to the higher ranking officials.

The three other officials charged, were involved with El Chapo’s previous escape.

El Chapo escaped from maximum-security prison using a tunnel he built in his cell at the Altiplano prison in July, 17 months after his incarceration. The tunnel measures 1.5 kilometers which was excavated under his personal shower in Altiplano prison. It appears that the drug lord used a motorbike on rails to make his getaway.

According to reports, the exit point was in a farmhouse which was used to hide the excavation under the jail.

Meanwhile, the son of El Chapo posted to Twitter, a photo of himself with his father following the news of the drug lord’s jailbreak. The said photo shows Jesus Alfredo Guzman Salazar with a man who looks like the fugitive and another man at a restaurant.

However, the picture revealed the location of the restaurant because Salazar forgot to disable the location function on his Twitter account.

But officials doubt if the said photo was taken in Costa Rica, according to reports. They believe the photo may be part of a plot to deceive officials as to El Chapo’s real location.

The Mexican government has offered a sum of $3.8 million to anyone who can give information as to his whereabouts.

In 2001, El Chapo also escaped maximum security.
