A group of friends who rented an Airbnb house near Paris made the horrific discovery of a decomposing body in the back garden.
The youths, who rented the property in the suburban town of Palaiseau for a weekend to hold a party, found the remains of a woman while exploring the grounds.
Her body was found at the bottom of the property which opens out into a wood.
Police have said the advanced state of decomposition makes it impossible to determine the cause of death, but they suspect foul play.
Bertrand Daillie, the deputy prosecutor for Evry, told AP news agency that the body appeared to have been deliberately covered by branches.
The renters were being questioned by police on Sunday.
According to Le Parisien newspaper, the listing was removed Sunday from Airbnb.
