A week after the attack on the police headquarters in Paris, the investigation into the motives of Mickaël Harpon still faces many gray areas, while no complicity has been identified at this stage for this attack. not claimed.

Solitary madness or planned attack of a radicalized with the help of accomplices or inspirers? "The main issue of investigations is to establish" whether the attacker, who worked since 2003 within the "PP", "or not benefited from complicity," sums up a source close file.

Heard Thursday morning by the Committee on the Laws of the Senate, the Minister of the Interior Christophe Castaner assured that "nothing" established at this stage that "there would be a collective organization around the author of the attack" .

Since the attack on October 3, which killed four people including three policemen, no claim has been published. To date, "we have not found any link between him and any terrorist organization," said the source close to the file.

A situation that reinforces the thesis of a solitary passage to the act, even if the killing of the prefecture meets the recurring slogan of the group Islamic State (IS) to attack the police and the police. representatives of the State.

- Imam stuck "S" -

Did the entourage of Mickaël Harpon, who bought his knives on the morning of the attack, know about his project or did he play a role in his radicalization? According to the antiterrorist prosecutor, the assailant was converted to Islam for about ten years and attended members of the movement "Islamist Salafist".

However, according to a source familiar with the matter, the mosque that the killer frequented in Gonesse was "not considered Salafist", even if an imam stuck S (State Security) officiates there.

"I saw him at the mosque, we simply greeted," told the latter to AFP, ensuring having had little contact with him. According to concordant sources, nothing at this stage establishes that this imam participated in the radicalization of the killer.

The wife of Mickaël Harpon, placed in custody on the day of the facts, was released, without prosecution at this stage. In his phone, the police found 33 SMS exchanged with the killer on the morning of the drama, with religious remarks.

The 38-year-old woman, suffering like her husband's deafness, assured the investigators that she had never heard of her husband's plans. She described the crisis that had shaken her the night before the attack and whose neighbors, who heard her repeatedly shout "Allah Akbar", were the witnesses.

Psychological problems, religious radicalization, professional frustration related to his disability ... "All these elements can very well be combined," recalls a regular anti-terrorism files.

- "serious failure" -

This unprecedented attack, carried out within the Directorate of Intelligence of the PP (DRPP), earned in recent days Christophe Castaner a volley of criticism and several summons to Parliament.

"This attack is in itself a serious failure," acknowledged the minister Thursday, referring to "signs of radicalization that have not been raised to the right level." "We need to understand" what happened to "prevent this from happening again," he added.

Mickaël Harpon, who had a clearance "secret defense", he transmitted sensitive information before acting out? The subject alarm in the ranks of the police and 160 investigators are mobilized to analyze a USB key found in the office of the killer.

The content of the key, on which were found videos of propaganda of the IS and police contact information, seems related to the duties of computer scientist Mickaël Harpon at the DRPP.

According to the first verifications, "there is no illegal transfer of data," said a source close to the survey Wednesday, adding that the analyzes were continuing.
