French Police Arrest Four Over Lyon Bomb Blast

French police have arrested four people over a package bomb explosion in the heart of the south-eastern city of Lyon last week that injured 13 people.

A police raid was also under way in a building in the Oullins suburb just south of the city, authorities said. The suspected bomber, a 24-year-old Algerian IT student, was among those arrested.

The man’s parents were also arrested and taken in for questioning, as was a second Algerian student who is a family relation, according to the Paris prosecutor’s office, which has jurisdiction over terrorism cases in France.

The suspect was previously unknown to police, Lyon’s mayor, Gérard Collomb, said.

Eight women, four men and a 10-year-old girl were injured in the explosion.

Eleven of the wounded needed hospital treatment, but none of their injuries are believed to be life-threatening. Some needed surgery to remove shrapnel, authorities said.

France has been on high alert following a wave of deadly jihadist terror attacks since 2015 which have killed more than 250 people.
