French police have arrested four people after a suspected parcel bomb exploded in Lyon last week, injuring 13 people.
The device, packed with screws and ball bearings, detonated outside a bakery on Friday afternoon.
One of those arrested, a 24-year-old man, is the suspected bomber, prosecutors say. Another man and a woman were also reportedly detained.
Police had been hunting for a man seen cycling near the scene of the blast wearing a balaclava and rucksack.
Anti-terrorist prosecutors are leading the investigation, co-ordinating with Lyon police and France’s internal security service, the DGSI.
French media report that one suspect is an IT student of Algerian nationality. A source told news agency Reuters that police arrested him in Lyon after tailing him in the street. It reportedly decided not to arrest him in his apartment in case there were explosives in the building.
The second suspect, according to local press, is a minor who attends a school in the city.
Two other people, a man and a woman, have also been arrested. They are reportedly the parents of one of the suspects.
Last week, police released a picture from CCTV footage of a person they believe carried out the bombing.
The explosion struck near the corner of two crowded pedestrian streets in Lyon’s historic city centre.
Investigators have recovered screws, ball bearings, along with a printed circuit, batteries and a remote-controlled trigger device.
