With Judicial Investigating Magistrate Elias Eid's questioning of four civilian witnesses Monday, judicial sources are expecting more arrests on Tuesday or Wednesday. The sources said State Prosecutor Said Mirza supervised the questioning of 10 suspects provided by the Internal Security Forces' Information Branch, all of which were cell phone dealers form either Beirut or Tripoli. It is believed calls were made in unison from several mobile phones before Hariri's assassination and then shut off together right after the bomb that killed him was detonated. The sources said Mirza examined the files of the suspects before sending them to the judicial investigator. The sources confirmed reports by An-Nahar that the international probe commission had raided the offices of one of the two major mobile companies in Lebanon, seizing some items they deemed suspicious. However, the sources did not reveal whether the company was the German-owned Alfa or the Kuwaiti-owned MTC. The sources also said the commission took the statements of several witnesses who had already visited its headquarters in Monteverde several times.
