Mexican authorities have found a tunnel that connects a wooden house with a state prison and two holes that were being used to store weapons, drugs and other contraband.

Axar.az reports citing Dailymail.

The authorities started a search operation after noticing an unusual earth movement in the prison of Reynosa, located in the north-eastern Mexican state of Tamaulipas and with the help of new technologies, they found the unfinished tunnel in a wooden house near the jail.

The Shawshank Redemption-style tunnel entrance was covered with wooden boards and bricks to avoid being discovered.

Francisco Garcia Cabeza de Vaca, the Governor of the state of Tamaulipas, said on his Twitter profile that it is believed that prisoners would have escaped from prison using this tunnel, which is 16 feet deep, 45 feet long and 4 feet wide.

The Public Security Secretariat said that after the tunnel was discovered, there was a special police operation to regain control of the situation.

They transferred four prisoners who were found to have dug the tunnel, reports said.
