Hello, teachers to have been arrested , having been arrested, have been arrested?

[Harry12345]

Teachers, which sentence is correct?

1 I knew him to have been arrested by the police.
2 I knew him having been arrested by the police.
3 I knew him have been arrested by the police.

I think 3 is correct. But I am not sure. Could you please tell me which one is correc and why? Thank you！

None is correct. One natural way to say this is, "I knew that he had been arrested by the police."

Harry, you don't need to say 'Hello, teachers'; just go ahead and ask your question.

It is especially unnecessary in your thread title.
