BFM TV reported the assailant had been caught after a manhunt that involved two police helicopters and more than 200 officers.

There was a shoot-out during the arrest and some policemen were slightly injured, it added. The victim was in a critical state, the news channel added.

The man, who police said stole the officer’s weapon, initially fled in a car before a crash forced him to continue on foot. Schools in the area were under police protection.

The motive for the stabbing was not immediately clear.

The incident comes a month after a female police administrative worker was knifed to death near Paris by a Tunisian national who had watched religious videos glorifying acts of jihad just before waging his attack.

Interior Minister Gerald Darmanin said he was travelling to the scene of today’s attack.
