Chelsea and England forward Callum Hudson-Odoi was arrested on Sunday following an argument with a woman.
The Metropolitan Police told The Sun that officers and London Ambulance Service were called in the early hours of Sunday morning “to a report of an unwell woman”.
The report added that the woman was taken to hospital and a man was arrested at the scene and remained in police custody.
Chelsea declined to comment on The Sun’s report.
Hudson-Odoi, 19, had made 17 Premier League appearances for Chelsea this season until the COVID-19 pandemic halted the campaign. He made his England debut last year and has a total of three caps for his country.
