“Police believe that it is, rather, something which would aim to facilitate the arrival at the catacombs, therefore the work of cataphiles,” he said, referring to clandestine catacomb explorers.

Cool, sewer catacomb people.

This is the best summary I could come up with:

A mysterious tunnel under construction has been discovered near a prison in southern Paris during routine electrical works, although police sources said it did not appear to be part of an escape plan.

The discovery was made on Tuesday by a technician from Enedis, which manages the electricity distribution network in France, who was working “in a well for electrical connections” about 450 metres from La Santé prison, a police source said.

“Bags of rubble and a bed” had been found at the scene, the source added.

Guillaume Durand, an official in the French capital’s 14th district, where the prison is located, said he doubted that an elaborate escape plan had been in the works.

“It’s a four-metre tunnel, in a cul-de-sac on rue de la Santé, but more than 500 metres from the prison,” he said.

The Paris catacombs, a massive underground ossuary, are one of the city’s most popular attractions and lure about 500,000 visitors a year.
