Real Sociedad forward Haris Seferovic was reportedly arrested following a heated argument with his girlfriend in San Sebastian on Sunday morning.
The 22-year-old and his partner are said to have been detained by the authorities for disturbing the peace in the Old Quarter area following Sociedad's 3-1 win over Barcelona.
According to Marca, the couple appeared before a judge after spending the night in jail, but left without charge after no complaints were filed.
It is unclear whether the argument between the pair turned physical.
