It is learnt that a Frenchman suspected to be in contact with one of the two brothers associated with the terrorist attacks in Paris last week has been arrested in Bulgaria when he was trying to cross into Turkey.  So, it can be expected that his thorough interrogation would throw light on the details of the plans and programmes behind those terrorist attacks along with the names of the other persons involved and would also help to curb any further attack not only in France but also in any part of the world.
