(CNN)A Spanish court has upheld a controversial verdict which convicted five men of sexually abusing a teenage girl rather than more serious offenses they were accused of, such as rape, sparking calls for further protests across Spain on Wednesday.
Spanish court upholds controversial 'Wolf Pack' conviction
The case -- which became known as "the Wolf Pack," after the name of a WhatsApp group on which the defendants and other friends chatted -- caused outrage and multiple demonstrations across Spain in April after the men were cleared of gang rape charges. The attack occurred during the 2016 running of the bulls festival in Pamplona.
The new ruling is the latest in a series of developments that have unsettled many in Spain.

During the trial, evidence was presented that the men, who denied wrongdoing, "pushed" the woman into a deserted hallway and told her to "shut up" before all engaging in sexual activity with her. She "adopted a passive, submissive stance" because she felt trapped and afraid, according to the sentencing document. One of th
