On Saturday, a knife attack occurred at the Gare de Lyon rail station in Paris, leaving three people injured.
Police, ruling out terrorism at this stage, apprehended the suspected attacker, who exhibited signs of mental disorders.
Paris police chief Laurent Nunes mentioned the discovery of medication, indicating ongoing treatment.
Two victims sustained minor injuries, while the third, in a more serious condition, was not in a life-threatening situation, according to the police.
The attacker, possessing Italian residence permits and legal status in France, used a knife and hammer in the assault.
Reports suggest he may be from Mali, though confirmation is pending from Nunes.
Despite France facing Islamist militant attacks, occasional incidents involve assaults by individuals with mental health issues.
