The ruling on working as a security guard for a building where vices are practiced?

Question:
He says: Honorable Shaykh, may Allah grant you success. A man works for a security company and guards a private residence for people of certain nationalities. Inside it, there is a bar, and various types of lewd acts are committed there. The question is: Inside it, there is a bar for intoxicants, and lewd acts are committed there. Is it permissible to guard it? And is his employment permissible?

Answer:
It is not permissible for him to remain silent about this in the lands of the Muslims. If he knows that this is a place for rebellion and immorality, he must inform the authorities so that appropriate measures are taken to remove this evil. It is not permissible for him to remain silent. It is not as if he is merely guarding it, in which case silence would be permissible. Yes.
