A police crackdown that aims to clear a poor suburb of petty crime and street vendors before the Paris 2024 Olympics is putting pressure on an overcrowded prison operating at almost double its capacity.

Villepinte is a grey, concrete detention centre in the suburb of Seine-Saint Denis. It lies 2.5 km from the Paris Arena Nord, set to host boxing and fencing competitions during the Games beginning on July 26.

It is among the most crowded prisons in France. Opened in 1991, Villepinte takes prisoners from the busy Bobigny courthouse nearby for pre-trial detention and short sentences.

"The penitentiary authority needs to prepare for the worst,” Eric Mathais, chief prosecutor at Bobigny, said in an interview.

Reducing inmate numbers ahead of the Olympics is unrealistic, Mathais said.

"We need to limit the number of people being imprisoned, but this is easier said than done as I am under extreme pressure from everyone to be clearly more repressive."

As of April 8, when Reuters visited Villepinte with local senator Corinne Narassiguin, there were 1,048 inmates for 582 places at the prison, according to director Pascal Spenle. The penitentiary cannot technically handle many more, Spenle said.

Yanis, a 20-year-old inmate, said he'd been on a waiting list for months for a prison work programme. One of his two cellmates, Adil, 25, said he had not met a reintegration councillor during seven months inside.

Ahead of an expected surge in the Olympics build up, Spenle said, Villepinte plans to transfer inmates to other prisons, freeing up 220 places. In the longer term the prison will get a new wing, he said.

In a letter to French prosecutors dated 15 January, Justice Minister Eric Dupond-Moretti called for "fast, strong and systematic responses” to infractions that may disrupt the Games.
