Four of the five men serving 15-year jail terms for gang-raping a teenager at a Spanish bull-running festival in 2016 have been handed additional prison sentences in a separate sexual assault case that happened a couple of months before, a court in Cordoba has said.

One of the men was sentenced to four years and six months, while the other three were sentenced to two years and 10 months for sexual abuse and breach of privacy.

The first wolf-pack case gained notoriety amid the global#MeToo movement and brought calls for changes to Spain's rape laws.

The five men raped the woman, then aged 18, at the entrance to an apartment building in Pamplona in July 2016 at the start of the popular San Fermin bull-running festival.

The men filmed the incident with their smartphones and then bragged about it on WhatsApp where they referred to themselves as "La Manada," or "The Pack".

The footage they shared on WhatsApp was used against them in court but also against the victim for her passivity during the act.

In April 2018, the men were each sentenced to nine years in jail for sexual abuse but judges acquitted them of the more serious offence of rape.

It was decided there had been no violence or intimidation - necessary for a rape conviction in Spain - and that the victim did not resist or fight back.

One of the three judges had argued that the men should be fully acquitted.

That decision - and the subsequent release on bail of the defendants - sparked nationwide protests.

In June 2019, Spain's Supreme Court found all five men guilty of gang rape.

The Madrid-based tribunal sentenced each defendant to 15 years in prison, overturning two previous rulings.
