It was reported the Afghan special forces commando had been in quarantine with his family after arriving on an evacuation flight from Kabul.
The raid was thought to have taken place on or around 31 August or 1 September and the individual is thought to be still in custody, according to Sky News.
It is not clear why he was arrested or if he has been charged with a crime.
Police can hold a suspect for up to 96 hours without charge if suspected of a serious crime. They can hold a suspect for or up to 14 days without charge if arrested under terrorism legislation.
The suspect had been placed in the hotel as part of Britain’s Covid-19 travel traffic light system which lists Afghanistan on the red list.
It means anyone returning from the country must check into government-mandated quarantine accommodation.
The Home Office didn’t have a comment.
A government spokesperson told the publication: “We don’t comment on individual cases.”
