The Conservative Party said he had been asked by the chief whip not to attend Parliament while an investigation is ongoing.
The man also faces allegations of an abuse of position of trust and misconduct in a public office.
A Met Police spokesman would not confirm the identity of the man or if he was an MP, but published a statement, saying: “In January 2020, the Met received a report relating to alleged sexual offences having been committed between 2002 and 2009.
“The offences are alleged to have occurred in London.”
He added: “A man… was arrested on suspicion of indecent assault, sexual assault, rape, abuse of position of trust and misconduct in public office.”
