Christophe Castaner also announced his intention to alert justice following remarks by the organizer of the event.

The rally in support of the author of the killing of the police headquarters in Paris, scheduled for Thursday in Gonesse, will be banned, said Wednesday the Minister of the Interior Christophe Castaner denouncing an "infamy". "The demonstration planned in Gonesse in support of the assassin of the police headquarters is an infamy and an insult to the memory of our police officers.I spoke with the prefect of Val-d'Oise: the gathering will be banned" said the interior minister on Twitter.

Christophe Castaner also announced his intention to alert justice following remarks by the organizer of the event. "I asked that the hateful remarks made by his organizer be denounced to the public prosecutor, on the basis of Article 40 of the Code of Criminal Procedure," added the minister, still on the social network. In a message posted on Facebook, Hadama Traoré, a political activist in Aulnay-sous-Bois, says that the author of the killing, Mickaël Harpon, "is not a religious extremist" and calls for a rally in front of the town hall from Gonesse (Val d'Oise) from 13h to 15h Thursday.

"A request for a classical event has been filed by Hadama Traoré, the analysis is underway, we will quickly give an answer," said the prefecture of Val d'Oise to AFP. Right and far right, but also some left, were upwind Wednesday against the organization of this homage to the killer of the prefecture of Paris, demanding its prohibition and for some the pursuit of its initiators.

"It's not tolerable"

Since Tuesday evening, several politicians call for an official ban on the event scheduled for Gonesse. "It is not tolerable, we can not understand that we accept a demonstration of support for a man who killed four policemen", criticized on Europe 1 the deputy LR of Alpes-Maritimes Éric Ciotti. On the left also, voices rose against this demonstration.

Yannick Jadot, boss of EELV, considered on Sud Radio "this form of legitimization of an absolutely abominable attack is scandalous". "We are really sometimes at the end of the abject and cynical," he lamented. The Radical Party of the Left, for its part, demanded "the outright ban on the demonstration of shame and filth" organized in support of the killer of the Prefecture of Police.
