The first police custody of three people, which began Friday at the end of the day, are extended.
This is the assailant's father and two people who hosted him, one recently in Thiais (Val-de-Marne) and the other when he arrived in France in 2009.
The homes of the father, located in Rambouillet, where Jamel G. had moved, and the landlord were searched Friday.
According to a source close to the investigation, the two people interviewed with the father form a couple who would have resided the assailant "at least administratively" in Val-de-Marne.
Jamel G., a 36-year-old Tunisian national holding a residence permit, had fatally stabbed a police official, Stéphanie M., in the entrance of the Rambouillet police station early Friday afternoon.
