Catalan regional police official Josep Lluis Trapero said in a press conference held this early afternoon that the investigation into the attacks in Catalonia is based on «the assumption that the authors were preparing these two attacks for some time in this house in Alcanar,» reports Le Monde. «We work with the hypothesis that the suspects were preparing both attacks for some time in this building of Alcanar. It was a group, we do not know the specific number, but we do not rule out having other attacks in mind. They are all identified», said Trapero. As for the identity of those arrested, «three are detained in Ripoll and one in Alcanar». The police chief also said that they are «three Moroccans and one Spaniard». None of them were known to the anti-terrorist services. Jose Luis Trapero also gave their age: the suspects were 21, 28, 27 and 34 years old. None of the 4 detainees arrested on the #Cambrils # and #Barcelona facts had a history of terrorism-related events — Mossos (@mossos) 18 août 2017
