A youth terrorist who beheaded a history teacher outside the school in France where he was teaching had reached out to students on the street and asked them to point out his victim.
The shocking revelation was made by anti-terrorist prosecutor Jean-Francois Ricard at a press conference on Saturday.
Ricard also said the attacker posted a photo of the teacher’s body on Twitter along with a message that he carried out the murder.
The victim was named as Samuel Paty, a 47-year-old father, and his killer was identified as Aboulakh A, an 18-year-old Russian national of Chechen origin.
The victim was beheaded after showing his class in a French school a cartoon of a naked prophet Mohammad.
It turns out that Mr Paty received threats before the gruesome murder that shocked France.
The Islamist terrorist was shot dead by police in the Paris suburb of Conflans-Sainte-Honorine on Friday evening after cutting off his victim’s head with a kitchen knife.
Parents confirmed that Teacher showed students a cartoon of a naked prophet earlier this month.
The portrayal of Mohammad with his buttocks was published by Charlie Hebdo, the satirical magazine that was attacked in 2015 by an al-Qaeda-linked gunman.
Twelve people were murdered in the publication’s offices in Paris after terrorists accused them of blasphemy before being gunned down themselves.
For Muslims, any portrayal of the Prophet is blasphemous.
In the recent attack, Aboulakh was heard shouting “Allahu Akbar” – Arabic for “God is greatest” – before posting a video of Mr. Paty’s beheaded head on social media.
Investigators tried to determine whether the attacker acted alone or with accomplices.
Nine people, including members of the attacker’s family, were arrested.
Four relatives of the attacker, including a minor, were arrested in the middle-class suburb immediately after the attack.
Five others were detained overnight, including two parents of students from the College du Bois d’Aulne, where the teacher was employed.
One of those arrested was the father of a student at Bois-d’Aulne College who posted a YouTube video asking people to complain about Mr. Paty’s behavior in class and the teacher “hit a thug” called.
Counter-terrorism prosecutors are investigating the attack on him, linking it to radical Islamism.
The killer had posted anonymous messages online describing French President Emmanuel Macron as “the leader of the infidels”.
In response, Mr. Macron said: “It was no accident that the terrorist killed a teacher because he wanted to kill the republic and its values.”
