French police today arrested 4 people suspected of being involved in the parcel bomb attack in central Lyons on 24 May.
A 24-year old Algerian national and a juvenile who is understood to be the suspects brother have been detained, along with a man and woman who are believed to be their parents.
Police have not released any further details other than the fact that the 24-year old applied for a French visa in 2017 in Algeria but did not complete the process.
He is believed to be a computer studies student in Lyon and he was arrested ‘without violence’ as he was getting out of a bus in the 7th arrondissement of Lyons.
The suspect was seemingly under surveillance and police said they chose not to arrest him in his apartment for fear there may be explosives inside.
According to police he remains ‘uncooperative’.
The bomb was detonated by a remote control device at around 5-30 p.m. local time outside a crowded street near a bakery in the historic 2nd arrondissement of the city centre, wounding 13 people, including a young girl.
All are described as having superficial injuries.
Following the explosion, a huge manhunt took place, with police issuing a CCTV picture of the suspect riding a pedal bike.
According to police, the device contained ball bearings and screws, along with a printed circuit and a remote detonation device.
The explosive involved is believed to be triacetone tripeoxide (TATP) , used in previous bomb attacks in France and known to be highly unstable.
The mayor of Lyon, Gerard Collomb said the suspect was previously unknown to police.
No terrorist group has claimed responsibility for the attack.
Islamic State has claimed responsibility for a number of previous attacks in France, which remains on high alert.
Heavily armed police and troops are a common feature in many major city centres.
Over 250 people have been killed in terrorist attacks in France since 2015.
