England international Billy Vunipola has confirmed he has been fined after an incident which saw him arrested in Mallorca on Sunday, with his club Saracens set to launch an internal investigation.

On Monday, widespread reports claimed Vunipola had been tasered by Spanish police in the early hours of Sunday morning, with an altercation taking place after he left a club in Palma.

Saracens later confirmed they were aware of an incident and said they would deal with it internally.

The number eight, who was born in Australia but has represented England 75 times, later released a statement of his own via his club, denying that any violence took place and confirming the police investigation was now closed.

"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," that statement 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 the law 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.

"I will obviously cooperate with the Saracens internal process and unreservedly apologise for any inconvenience to all involved."
