Investigators on Sunday researched the background of a 20-year-old Frenchman born in Chechnya who killed one man and wounded four other people during a stabbing spree in central Paris.
According to a judicial source speaking to France 24, the man’s parents have been taken into custody for questioning. Later Sunday, the same source said a friend of the suspect had been arrested and taken into questioning in the eastern French city of Strasbourg.
An assailant shouting “Allahu akbar” was shot dead by police in central Paris late Saturday, minutes after he attacked people near the city’s main opera house a popular neighbourhood full of bars, restaurants and party-goers every weekend.
The suspect has not been named, but sources close to the inquiry say the Frenchman was on an anti-terror watchlist of suspected extremists, although he did not have a criminal record.
