Police union official Loic Travers told colleagues that the attack seems to have started in a workplace and lasted elsewhere in the huge police compound throughout the street from Notre Dame Cathedral.
The number of people injured wasn’t immediately understood.
Travers explained the rationale is unknown, but the 20-year police worker supposedly responsible for the attack functioned as a secretary at the intelligence unit also hadn’t posed known issues until Thursday.
He explained he couldn’t recall an attack of the size against officers.
Emery Siamandi, a worker at the police officer, said that he heard gunshots and instantly saw two officers come out a workplace yelling. A third officer, that Siamandi explained as the individual who shot and killed the assailant, came from his knees, too in tears.
The assault came a day after tens of thousands of officers flew in Paris to protest low salaries, long hours and raising suicides in their positions.
France’s prime minister, interior minister along with also the Paris prosecutor were in their way into the scene.
The Paris prosecutor’s office said that no info could be offered in this stage.
The area, among Paris’ funniest tourist attractions, was locked down, the Cite subway stop was shut and also the bridge between Notre Dame and the headquarters building was blocked away.
Extremists have targeted French authorities in France in the past few decades.
Back in 2016, an assault motivated by the Islamic State team murdered a police officer along with his companion administrator, in their house in front of the child.
