French police investigating the fatal stabbing of two young women in the southern city of Marseille, an attack claimed by ISIS, have arrested two men, a judicial source said Wednesday.

The pair, aged 24 and 29, were arrested on Tuesday in Toulon, about 65 km east of Marseille.

Ahmed Hanachi, a 29-year-old Tunisian, fatally stabbed the two women at Marseille’s Saint-Charles train station on October 1, before being shot dead by police.

ISIS claimed responsibility, but French investigators have not found any evidence linking the attack to the jihadists.

A judicial source said of the arrests: “The 24-year-old man may have hosted the killer Ahmed Hanachi during one of his visits to Toulon.”

The source added the suspects were together when they were arrested.

Police have focused their investigation on Hanachi’s family, arresting four of his siblings in the days following the attack. Two have been freed.

The other two siblings, brothers Anouar and Anis, await extradition after their arrests in Switzerland and Italy, respectively.

French investigators suspect Anis of complicity in the Marseille attack.
