Cengiz Yalçın

Cengiz Yalçın was one of three men arrested by Spanish authorities on Wednesday, 1 August 2012, on suspicion that they were planning a terrorist attack for al-Qaeda.

Cengiz Yalcin, a Turkish national, was characterised as a "facilitator" in the cell. He was identified as a site manager on the company's website, and he had participated in a construction project at Western Beach in July 2012. After being informed that it was impossible, Yalcin questioned whether the photographs could be acquired in a light aircraft, claiming that he needed the image for a construction project he was undertaking at that location.

Spanish investigating magistrate Pablo Ruz closed the investigation on March 21, 2013, at least partly because of a lack of cooperation from US authorities. The three men were freed without charge after serving nine months in solitary confinement. Adamov and Magomedov were subsequently deported to Russia while Yalcin remained in Spain.
