The Groucho Club was opened in 1895 as a more relaxed alternative to traditional gentlemen’s clubs and has a long association with A-list celebrities.
A council spokesperson said the decision to suspend its licence “follows reports that a serious crime may have taken place at the premises in circumstances linked to a breach in the premises licencing conditions”.
“The allegations are subject to an ongoing police investigation and we cannot comment further at this stage,” they said.
The Met said its investigation into “a recent serious criminal offence” was still taking place so it could only provide a limited amount of detail.
It added further information would be released “when possible”.
It is understood the fact that a police investigation is taking place was only publicly revealed because the force had to apply for the club’s licence to be suspended, with the hearing having taken place in private.
The Groucho Club has been approached for comment.
