MADRID, Spain (CNN) -- A Spanish judge has charged another Moroccan suspect in the March 11 Madrid train bombings, making a total of 18 people who have been jailed and charged in the case, Spain's state-run news agency EFE reported.
The latest suspect, Fouad El Morabit, was charged Monday with collaborating with a terrorist group, EFE reported.
He was among three Moroccans who were arrested in recent days in connection with the bombings, but their arrests were not made public until Monday, a National Court spokeswoman told CNN.
El Morabit had been arrested twice before in the bombings case but released. He was first arrested March 25 but was set free on March 30, without charges, only to be rearrested hours later that day.
He was arraigned for a second time on April 2 and released without charges but required to report daily to police or court officials because authorities considered him to be of interest in the case, the spokeswoman told CNN.
Court officials told CNN that El Morabit studied aeronautical engineering and radio electronics in Madrid and Germany and shared a flat with a Syrian man, Basel Ghayoun, who is among the 18 people charged in the bombing case.
El Morabit had talked to several of the other suspects in the case before the March 11 bombings, and he talked to some of them the same day as the bombings, court officials said Monday, according to the EFE report, which also said El Morabit had declared his innocence in the closed-door arraignment before Judge Juan del Olmo.
The other two Moroccans were arrested in the Madrid southern suburb of Parla, the court spokeswoman told CNN. Their identities were not immediately revealed.
Parla is close to the southern suburb of Leganes, where on April 3 a group of suspected Islamic terrorists linked to the train bombings blew themselves up as police raided their apartment hideout. Since then, the southern suburbs have been under close scrutiny as police hunt for other suspects in the case.
Arraignments for the two arrested in Parla were expected later this week, the court spokeswoman said.
