The feds on Thursday busted the brother of terrorist Syed Rizwan Farook in connection with a marriage scam that only came to light after last year’s jihadist massacre in California, officials said.

Farook’s brother Syed Raheel Farook, 31, his Russian wife Tatiana Farook, 31, and her sister Mariya Chernykh, 26, were all taken into custody from their homes in the eastern suburbs of Los Angeles, prosecutors said.

All three were charged with marriage fraud, federal conspiracy and making false statements.

Their phony marriages were the basis for filling out immigration papers, obtaining bank accounts and driver’s licenses, officials said.

The arrests had no direct connection to the terrorist attack carried out by Syed Rizwan Farook and his wife, Tashfeen Malik, who slaughtered 14 people on Dec. 2 at the Inland Regional Center in San Bernardino.

Feds investigating the bloodthirsty duo unearthed the allegedly shady marriages of Syed Raheel Farook and family friend Enrique Marquez, who is married to Chernykh.

Marquez, 24, is in jail awaiting trial on charges that he provided guns to Syed Rizwan Farook.
