England back-row Billy Vunipola was arrested in Mallorca, Spain, on Sunday for resisting arrest and has been fined €240 ($257) for the incident.
In a statement shared by his club Saracens, Vunipola denied reports that he had acted violently to cause the arrest, though Spanish police claimed he slapped an officer.
"I can confirm I was involved in an unfortunate misunderstanding when I was leaving a club in Mallorca on Sunday, which got out of hand," his statement, released Monday, read.
"Contrary to media reports, there was no violence, no fight and I did not threaten anybody at any stage, with bottles or chairs or anything else.
"I was charged with resisting arrest and, following an 'express trial,' I have paid a fine of €240. The Spanish police investigation is now closed and I am flying back to the UK today."
According to a report in the Ultima Hora newspaper, Vunipola was tasered twice by police after threatening customers and security personnel and removing his shirt in a bar named Epic in Palma early on Sunday.
The report added that the 31-year-old was handcuffed by the police and taken to the Son Espases hospital in Palma, where he was sedated, before being taken to court on Sunday afternoon.
"In the early hours of yesterday morning, at 4.30 am, the National Police proceeded to arrest a 31-year-old foreign man, for a crime of disobedience and attacking a police officer," a spokesperson for the National Police in Mallorca said.
"The police officers tried at all times to get him to calm down, but the man would not listen to reason. At that moment, the man pushed and slapped an officer and a policeman pulled out his electric stun gun and fired, hitting a projectile in the wallet, which did not discharge.
"A second projectile was then fired, which did the job, and it was then that the officers jumped on him and proceeded to immobilise him by shackling him, later taking him to Son Espases hospital for assessment and arrest."
Saracens had earlier issued their own statement saying they would deal with the incident "internally." Vunipola added that he would "obviously cooperate" with their process.
Vunipola has made 75 appearances for England, most recently featuring in the narrow Rugby World Cup semifinal defeat to South Africa in October.
He played for Saracens against Bath in their 15-12 win on Friday.
