PARIS, Oct. 2 (Xinhua) -- The man who stabbed to death two women at a railway station in Marseille, southeastern France, had seven different aliases and known for public offenses, but no links with terrorism have yet been established, Paris Prosecutor Francois Molins said Monday.

Molins said the suspect in the fatal knife attack, claimed by the Islamic State (IS), appeared to be a 30-year-old Tunisian who illegally entered France earlier this year.

He had been arrested by police in the central French city of Lyon two days prior to the assault for shoplifting. He then presented a Tunisian passport naming himself as Ahmed H born in 1987. He was released the following afternoon without charge.

Molins added that the suspect told police he was homeless, divorced and suffered from drug abuse.

"This identity and the different aliases are unknown to the specialized anti-terrorist services," he told reporters, adding his office was verifying the authenticity of the Tunisian.

On Sunday afternoon, the suspect armed with two knives stabbed to death two cousins, aged 21 and 20 years at Saint-Charles station in Marseille before being shot dead by military soldiers who were patrolling the zone.
