The new trial began with the prosecution alleging that four members of the same group sexually abused an unconscious woman after a night out in Cordoba, just weeks before they made the trip north for the Running of the Bulls fiesta.
The men, who had a WhatsApp group named "La Manada" - which translates as "The Wolf Pack" – in which they boasted about finding women to attack - are currently serving 15-year sentences given to them by the Supreme Court for a rape in a case which became notorious in Spain and sparked the nation’s own #MeToo movement.
