A Spanish citizen, Gabriel Montoya is so far the only person to have been convicted and sentenced for an offence connected to the train bombings. Commonly known as "El Gitanillo", Montoya was accused of having participated in the theft of the explosives used in the bombs. It was found that he accompanied Emilio Suárez Trashorras to the Conchita mine from where the dynamite was stolen. It is also alleged that he carried 20 kilos of explosives to Madrid, where it was collected by Jamal Ahmidam, said to be the operational organiser of the attacks. Because he was only 16 years old at the time, Montoya was tried as a minor and sentenced to 6 years internment in a youth centre, to be followed by 5 years of restricted liberty.
