The driver of a Spanish train that derailed, killing at least 80 people, was under police guard in hospital on Thursday after the dramatic accident which an official source said was caused by excessive speed.
The eight-carriage train came off the tracks, hit a wall and caught fire just outside the pilgrimage destination Santiago de Compostela in northwestern Spain on Wednesday night. It was one of Europe’s worst rail disasters.
The source had knowledge of the official investigation into a crash which brought misery to Santiago on Thursday, the day when it should have celebrated one of Europe’s biggest Christian festivals. Authorities canceled festivities as the city went into mourning.
The Galicia regional supreme court said in a statement the judge investigating the accident had ordered police to take a statement from the driver.
He was being formally investigated and under police guard but not under arrest, the court said. He was in hospital but it was not clear what kind of injuries he had suffered.
