Billy Vunipola, former forward of England and the rugby club Saracens, was restrained with a shock device and then arrested after an alleged violent incident in Majorca, Spanish media reported on Monday.
Saracens say they are aware of an incident their player was involved in and will deal with it internally.
The Majorca-based newspaper Ultima Hora reported that police officers shot 31-year-old Vunipola twice with a Taser shock device after they were called to a bar in the island’s capital, Palma.
According to the report, Vunipola at one stage took off his shirt and confronted passers-by. It eventually took the intervention of eight police officers to calm him down and handcuff him.
He was then taken to a hospital where, according to the report, he had to be sedated.
The newspaper’s website shared a video of a handcuffed Vunipola, as he was brought out of a police vehicle with other men and escorted to court.
A statement from Saracens on social media stated that the club will not make any further comment until its internal investigation into the events has been concluded.
Vunipola is expected to leave Saracens at the end of the season. It was previously speculated that he might settle in France, although there was no confirmation.
He played 75 games for England and made his Test debut in 2013 against Argentina.
Vunipola is not currently part of the England squad.
He started for Saracens in the second half in the club’s 15-12 win against Bath on Friday. The club will not play their next game again until May 11.
