“French newspaper Le Parisien cited a police source as saying the suspect was arrested at about 3:25am local time (02:25 GMT) outside the bank’s local headquarters in the city’s 8th arrondissement as he tried to light a device consisting of a five-litre (1.3-gallon) container filled with an unidentified liquid and an explosive charge made up of about 650 grams (23 ounces) of powder”

“The National Terrorism Prosecution Office told the Reuters news agency the suspected offences included attempted destruction by fire or other dangerous means in connection with a 'terrorist plot', as well as the making, possession and transport of an incendiary or explosive device with intent to carry out dangerous damage”

“The probe also includes a charge of participation in a 'terrorist' criminal association, covering potential links to accomplices or a broader network, it said”

“Interior Minister Laurent Nunez stated that vigilance remains at a very high level and thanked security and intelligence forces for their mobilization”

“Earlier in the week, Nunez had said that authorities had stepped up the personal protection of some figures from the Iranian opposition and increased security around sites that risked being targeted, including sites linked to US interests and to the Jewish community”
