A suspect shot dead by police after the beheading of a history teacher near Paris was an 18-year-old Chechen refugee unknown to intelligence services who posted a grisly claim of responsibility on social media minutes after the attack, officials said Saturday. France’s anti-terrorism prosecutor’s office said authorities investigating the killing of Samuel Paty in Conflans-Sainte-Honorine on Friday arrested nine suspects, including the teen's grandfather, parents and 17-year-old brother, the AP reports. Paty had discussed caricatures of Islam’s Prophet Muhammad with his class, leading to threats, police officials said. Islam prohibits images of the prophet, asserting that they lead to idolatry. The officials could not be named because they were not authorized to discuss ongoing investigations.
French anti-terrorism prosecutor Jean-Francois Ricard said an investigation for murder with a suspected terrorist motive had been opened. Ricard told reporters that the Moscow-born suspect, who had been granted a 10-year residency in France as a refugee in March, was armed with a knife and an airsoft gun, which fires plastic pellets. His half-sister joined the Islamic State group in Syria in 2014, Ricard said. The prosecutor said a text claiming responsibility and a photograph of the victim were found on the suspect's phone. He also confirmed that a Twitter account belonged to the suspect. It posted a photo of the decapitated head minutes after the attack along with the message "I have executed one of the dogs from hell who dared to put Muhammad down."
