Spanish soccer star Jenni Hermoso has lodged a criminal complaint over the unsolicited kiss by football federation boss Luis Rubiales after Spain's victory in the Women's World Cup, the national prosecutor's office said on Wednesday.

Hermoso gave her testimony on Tuesday and the complaint will be processed "as soon as possible", the prosecutor added.

With the complaint, Rubiales could face criminal charges in addition to the ongoing inquiryby Spain's top sport court for "serious misconduct" and an investigation by world soccer governing body FIFA, which has provisionally suspended Rubiales from office.

Neither Hermoso's representatives nor Rubiales were immediately available for comment.

Rubiales grabbed Hermoso's head and kissed her on the lips during the medal-giving ceremony that followed Spain's 1-0 victory over England in the Women's World Cup final on Aug. 20.

Late last month, the prosecutor for Spain's High Court said Rubiales could face a sexual assault charge, which carries a prison term of between one and four years, if Hermoso were to file a complaint.

The High Court has jurisdiction over the case as the incident took place abroad - in Sydney, Australia.

Hermoso said she did not want to be kissed, and that she felt "vulnerable and a victim of an aggression". Rubiales, who has so far refused to resign despite heavy pressure, said the kiss was "spontaneous, mutual, euphoric and consensual".

Rubiales' behaviour has sparked outrage in Spain and abroad. He also grabbed his crotch while standing close to Spain's Queen Letizia and her 16-year-old daughter during the final match.
