A Queens rabbi who is being sued by the congregants of a Lower East Side synagogue for trying to sell their $13 million building out from under them and allegedly make off with the profits, is now under investigation by federal as well as state officials, The Post has learned.

Rabbi Samuel Aschkenazi, leader of the right-wing Hasidic sect, Ger, was served with papers by two FBI agents as soon as he stepped off the witness stand in Manhattan Supreme Court in the civil case Monday.

Aschkenazi was set to sell the House of Sages of Israel at 25 Bialystoker Place to developer Todd Fine before the state attorney general stepped in last fall and put hold on the transaction.

Aschkenazi's attorney, Michael Bachner, confirmed to The Post that the rabbi is being probed by US Attorney Preet Bharara.
