Alaves defender Olivier Verdon has been arrested on suspicion of assault.
According to reports in Galician newspaper La Voz de Galicia, the 23-year old was arrestd by police following allegations that he attacked his girlfriend at a hotel in Vitoria.
Verdon signed for the Vitoria-based club this summer in a €450,000 deal from Ligue 1 side Sochaux, and had been temporarily staying in the hotel following his move to Spain.
