In the camp held in Barcelona, the players of "West Brom" were so relaxed that they became famous for their silly antics.
It is reported that four footballers whistled a taxi car left near the "McDonalds" restaurant and drove it to their hotel.
The frightened taxi driver called the police, who briefly arrested Jonny Evans, Gareth Barry, Jake Livermore, and Boaz Myhill.
Later, the club issued a public apology and assured that they will make every effort for the players to cooperate with law enforcement and resolve this unpleasant incident.
