The five people in police custody Monday in the investigation of the killings at the Paris police headquarters were all released without charges against them, a judicial source said Wednesday.

Two of them were released Tuesday night, including an imam for radicalization who officiated in a prayer room Gonesse (Val-d'Oise) attended by the killer. The three others were extended Tuesday night for 48 hours, but were finally interrupted on Wednesday, according to the source.

These five people were presented as relatives of Mickaël Harpon, who killed four colleagues on October 3 in the premises of the prefecture before being shot by a police officer. They had been arrested on the night of Sunday to Monday in the Val-d'Oise. Searches had then been held in several communes of the department, including Gonesse, where lived Mickael Harpon.

The investigation aims to understand if the attack is the result of a solitary madness on the background of autoradicalisation or whether Mickaël Harpon benefited for his murderous project of accomplices or inspiring. Computer scientist employed since 2003 at the police headquarters, Mickaël Harpon, 45, was in charge of maintenance at the Directorate of Intelligence (DRPP). He had been converting to Islam for about ten years and was dating members of the Salafist movement.
