Jose Carlos Serna escaped from jail twice. His wife sent fake faxes from court saying release him, so they did.
Sr Serna was in a cell at Arganda del Rey courthouse awaiting trial when officers received a fax purportedly from a regional court.
It was followed by a phone call from someone claiming to be a court official, corroborating the release order.
Officers did try to verify the order, but their calls went unanswered. When they received a second call, confirming Serna's release, he was freed and put into a waiting taxi.
Both of the calls were from his wife, Gema Maria Serna, who police tracked down to a house in the northern suburb of San Lorenzo del Escorial.
Last time Serna used the trick on police he escaped from Valdermoro jail.
