He is 34 and authorities consider him a member of the ultra-left, according to a source close to the case.

Overnight curfews in violence-hit zones of French cities helped bring some calm after the nation's worst unrest in years, ahead of more demonstrations planned for the weekend, the government said.
The French government tried to reassure the public it had learned from security oversights that left the centres of cities such as Paris, Marseille and Lyon largely unprotected from rioters and looters moving in after protests.
Mr Lecornu said restrictions may be extended further into the week if the unrest continues.
High school pupil strikes and protests against falling standards and growing dilapidation have converged with a wider outpouring of fury at rising prices and the feeling that health, housing and welfare needs are also no longer being met.
