Police arrest man with links to Paris knife killer

French police have arrested a man with suspected links to the killer of a police commander and raided several houses, the prosecutor’s office said, part of a deepening investigation into last week’s attack claimed by IS.

The police probe is focusing on suspected associates of Larossi Abballa, the Frenchman of Moroccan origin who pledged allegiance to the Islamist militant group and told police negotiators during the attack that he had answered a call to “kill infidels at home with their families”.

“There was a chance that these people might carry out other attacks against police officers. We were removing any doubt,” said the Versailles prosecutor leading the investigation.
