“It does state in Jude that the angles that left their first estate (life form) are now in chains in Tarsus I do believe.”
Jude 1:6. And the angels who kept not their principality but forsook their own habitation, he hath reserved under darkness in everlasting chains, unto the judgment of the great day.
(Principality...That is, the state in which they were first created, their original dignity.)
“These angles left their spiritual bodies and took on flesh so as to mate with the daughters of man. That was their great sin taking on flesh and that is why they are in chains.”
I didn’t find anything on that in Jude.
