Technician finds four-meter-long tunnel in a dead-end street on Rue de la Santé, more than 500 meters from the prison. Police assume that the tunnel was intended to make the route to the world-famous catacombs of Paris easier and was dug by secret researchers.
The authorities sent an engineer to the site to fill the hole. The Paris police still give the all-clear and say the tunnel is not part of a sophisticated prison escape route. It is part of the former underground quarries, located around 20 meters below the French capital, which are now one of the most popular attractions in Paris.
