In the investigation into this attack, carried out by the national anti-terrorism prosecution, "there are no longer any police custody in progress," said this source.

The father of Jamel Gorchene, as well as a couple who had administratively domiciled the author of the attack, had also been placed in police custody before being released, Tuesday for the first, Sunday for the couple.

Jamel Gorchene, a 36-year-old Tunisian national with a residence permit, fatally stabbed a police officer, Stéphanie Monfeture, in the throat in the entrance to the Rambouillet police station early Friday afternoon.
He was killed by gunfire from a police officer.
This delivery driver had no criminal record and was unknown to the intelligence and justice services.

According to the national anti-terrorism prosecutor Jean-François Ricard, the author, whose radicalization was "hardly questionable", presented "certain personality disorders".
