According to reports, officers made their way to the 19-year-old’s apartment after a woman rang police and an ambulance at 4am.
Hudson-Odoi is believed to have made contact with the woman on social media and invited her to his penthouse.
A neighbour said the woman arrived at Hudson-Odoi’s apartment at around 8pm on Saturday: “She looked very glamorous, like the sort of girl you’d see on Love Island.
“She had very posh Louis Vuitton luggage with her.”
The neighbour added: “The place has been crawling with police.
“A spa area on the roof has been taped off but I’ve no idea if that’s the same incident.”
The Metropolitan Police said: “Police and London Ambulance Service were called at 03.53hrs on Sunday 17 May to a report of an unwell woman.”
The Met confirmed a man who was arrested remains in custody while the woman was taken to hospital after complaining of feeling unwell.
