<p>RAMBOUILLET, France — Masked and in silence, hundreds of police officers, family members and others paid homage Monday to a French police official killed inside her police station in what authorities are investigating as an extremist attack.</p>
<p>Family members, colleagues and friends of the victim joined local officials at the tribute ceremony in front of the town hall of Rambouillet, a quiet Paris suburb rocked by Friday’s stabbing by a suspected Islamic extremist.</p>
<p>“A flame has been extinguished in everyone’s heart,” Mayor Veronique Matillon told the crowd, honoring a woman who “was killed while serving out her functions." The victim was identified publicly only as Stephanie M.</p>
<p>Police unions called for gatherings in front of police stations across France at the same time as the one in Rambouillet.</p>
<p>Meanwhile, a group of imams also called for a gathering in Rambouillet to honor the slain official and show their support for police. The group said it was important to “firmly condemn all blind violence carried by a radical ideology” that hurts efforts to unite the French.</p>
<p>French police killed the 37-year-old Tunisian attacker shortly after he stabbed the unarmed administrative employee on Friday at the entrance of her police station.</p>
<p>Three people remain in custody as part of the anti-terrorism investigation seeking to identify potential accomplices and motives, a judicial official said Monday. Authorities said the attacker didn’t have a previous criminal record and hadn’t been flagged for radicalization.</p>
