An ex-Colombian drug trafficker has testified that the president wanted $250 million, but settled for less. Former officials have rejected the allegations, saying they are "false, defamatory and absurd."
Colombian trafficker Alex Cifuentes, who described himself as Guzman's former right-hand man, said the once-head of the Sinaloa cartel had bribed Pena Nieto in 2012, when he was president-elect, in exchange for the government ending its manhunt to find him.
Cifuentes admitted that he first discussed the bribe with prosecutors in 2016, when he began cooperating with US authorities.
Pena Nieto had first asked for $250 million, but later settled for $100 million, Cifuentes said he told prosecutors. After the bribe was paid, Pena Nieto sent a message to Guzman that he longer had to live in hiding, Cifuentes testified.
The former Mexican president has denied any wrongdoing, with his former chief of staff taking to Twitter to reject the allegations.
"The declarations of the Colombian drug trafficker in New York are false, defamatory and absurd," said Francisco Guzman (no relation to "El Chapo") on Twitter.
The ex-official noted that Pena Nieto's government "located, detained and extradited" the notorious drug lord. "From the beginning, it was a priority for the security cabinet."
Mexican drug baron "Shorty" Guzman is not the first prisoner to want to escape the thick walls, bars, guards and search lights of jail. Here are some of the most spectacular, if not always successful, prison breaks.

Maximum security in Mexico
In July 2015, Mexican drug kingpin Joaquin "El Chapo" Guzman escaped the Altiplano prison through a tunnel under his cell's shower - the second time in 14 years that he managed to flee a maximum-security prison. Guards discovered a deep hole with a ladder that led to a tunnel that in turn led to a building on a hill surrounded by pastures.

Nice try
Not as clever as Guzman: In 2011, the wife of inmate Juan Ramirez Tijerina visited her husband in a Mexican prison, where he was serving a sentence for illegal weapons possession. She brought along a large suitcase she planned to lug him out with again. Prison guards, however, found the young man inside - curled up inside in the fetal position.

H-Block 7
In 1983, 38 Irish Republican Army (IRA) inmates broke out of The Maze, considered to be one of Europe's most escape-proof prisons. The Maze was the main prison in Northern Ireland for sentenced republican and loyalist paramilitaries. The inmates used smuggled guns and knives to overpower staff, and hijacked a kitchen van to drive to the main gate, and out of the compound.

The Alcatraz escape
With the help of sharpened spoons and an improvised drill, three bank robbers managed to burrow their way out of their cells in Alcatraz high security prison in the San Francisco Bay in 1962. To fool the prison guards at bay, the trio placed dummy heads in their beds. Once they were out, they used an inflatable raft made out of raincoats - and vanished.

Daring flight
It sounds like a script for Hollywood blockbuster: Pascal Payet twice used helicopters for his dramatic prison breaks. In 2001, the convicted murderer fled from a prison in a French village using a hijacked helicopter. In 2007, he again used a helicopter for a get-away. Previously, he had helped organize the escape of three captives who had been in jail with him - again using a helicopter.

Most wanted fugitive
Awaiting trial, serial killer Theodore Robert Bundy escaped from a county law library by jumping from a window. Re-arrested and sent to jail in Colorado, Bundy lost 30 pounds so he could escape again through a small light fixture hole in the cell ceiling. Bundy spread terror across the US, killing numerous women between January 1974 and 1978, when he was finally recaptured and sentenced to death.

An Easter escape
Inmate Walter Stürm, imprisoned for stealing offenses, left a smug note in his cell after his get-away from a Swiss prison in 1981. "Off hunting Easter eggs," the note read. Stürm had sawed through the bars on his window, let himself down to the ground to the prison yard and fled to freedom by using a ladder. It was his third prison break.

Busting out
In June 2015, two convicted murderers, David Sweat and Richard Matt, broke out of a maximum-security prison in upstate New York, cutting holes in the walls of their adjoining cells, and working their way through a maze of catwalks and pipes to emerge from a manhole. The duo did a practice run the night before the escape. Matt was later killed by police, while Sweat was recaptured, badly injured.
