Two runaways escaped from Tihar jail in India on the weekend, digging a tunnel under a wall, and climbing another for their way out, said the Indian officials.
The two, charged with robbery, were awaiting trial before their escape.
Authorities announced that one of the prison-breakers was found and captured while the search for the other still continues.
Reports said this is the first incident that prisoners were able to dug their way out of the jail as Tihar jail is known to be one of Asia’s top security prisons, where many of India’s feared criminals stay.
The Times of India reported that the escaped prisoners, named Faizan and Javed, are said to have climbed the walls of the jail buildings, digging a tunnel under a wall and escaped through a drain pipe.
Officials say they are still investigating the incident.
"They escaped sometime on Saturday or Sunday,” said Tihar deputy inspector general Mukesh Prasad.
“We will find out how they managed to escape,” he added.
“It is too early to say how and when they staged the jail break.”
