The Raid thought they were intervening for a man entrenched with his wife and children whom he threatened to kill.. A 16-year-old man was taken into custody on Wednesday 24 May for disclosing false information.

He is suspected of having produced a hoax leading the police and rescue to intervene in Pontoise, at the end of the day. An important mechanism has been put in place. A security perimeter has been deployed in the Louvrais district. Traffic was diverted for several hours. All for nothing.
