Manchester United have said that their captain Harry Maguire was involved in an "alleged incident" in Mykonos.
Various reports have stated that England international was arrested on the Greek island following an incident outside of a bar. The club has not confirmed the details of these reports.
The 27-year-old centre-half was allegedly spotted by police having an altercation with other British tourists last night, local media reported.
When the officers intervened, three Englishmen are alleged to have fought back verbally and physically.
As a result, three people were detained in the early hours of Friday - among them the Manchester United captain.
Manchester United said in a statement: 'The club is aware of an alleged incident involving Harry Maguire in Mykonos last night. Contact has been made with Harry, and he is fully co-operating with the Greek authorities. At this time we will be making no further comment.'
Maguire is on an end-of-season break following United's elimination from the Europa League at the hands of Sevilla on Sunday.
