Surveillance camera footage shows the suspect in the shooting at a Paris Kurdish cultural center walking into a barber shop, gun in hand, before being overpowered by men at the back of the premises.
The 69-year-old had opened fire on several people outside the cultural center in the French capital, killing three. The pensioner later admitted his intention was "to murder migrants" in a city north of Paris, with a large population of foreign origin.
On Sunday, the prosecutor's office said the man was driven by "pathological hatred".
