LYON, France (AFP) — France’s prison service said Saturday it had launched an investigation after a man escaped by smuggling himself into his cellmate’s bag as he left jail, having served his sentence.

The 20-year-old prisoner escaped from Corbas prison, near Lyon, southeast France, on Friday, broadcaster BFMTV reported.

The inmate was serving several sentences, the prison service said in a statement to Agence France-Presse (AFP).

He “took advantage of the liberation of his fellow inmate to hide himself in his luggage and get out,” the statement said.

The escaped prisoner was also under investigation in a case linked to organized crime, a source close to the affair told AFP.

An internal investigation is underway and Lyon prosecutors had opened their own investigations, the prison service added.
