Security authorities in France have arrested four people including a young Algerian man deemed the main suspect in the letter-bomb attack last week in Lyon, south-eastern France, which wounded 13 people.
A 24-year old computer science student from Algeria has been identified as the main suspect for the blast on Friday afternoon, in front a bakery.
Authorities did not reveal his name. CCTV footage released last week led to the suspect believed to be the bomber in Lyon’s historic city center. The footage showed a man partly masked leaving the scene on bicycle.
The man is not known to police and no one has claimed responsibility for the attack.
Police arrested another man and two other people believed to be the suspect’s mother and young brother who is a high school student.
The parcel contained triacetone triperoxide (TATP) mixed with screws and ball bearings. The home- improvised device wounded 13 people, 11 of whom are still in hospital, reports say.
