Midfielder Gylfi Sigurdsson is the Everton player who was recently arrested by the police on suspicion of a sexual offence.
The case allegedly involved an underage victim.
On Tuesday, Everton reported that an unnamed player has been provisionally suspended pending a police investigation.
The name of the 31-year-old Sigurdsson soon appeared in British media.
Icelandic media have now confirmed that it is indeed Sigurdsson who was arrested on Friday and released on bail the same day.
Further details about the case are unknown.
Sigurdsson has been playing for Everton since the summer of 2017, who paid Swansea City almost €50 million for him.
So far, the Icelander has played 156 official games for the Liverpool club.
Last season he regularly wore the captain's armband.
In 2009, Sigurdsson made his professional debut while playing for Reading - he came to England from Iceland at a young age.
In the years that followed, the 78-time Icelandic international also played for Hoffenheim, Tottenham Hotspur and therefore Swansea City and Everton, among others.
Without Sigurdsson, Everton are currently preparing for the new Premier League season, which starts for 'The Toffees' on August 14 with a home game against Southampton. Everton has recently been led by manager Rafael Benítez.
